Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The condensed consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and should be read in conjunction with the audited consolidated financial statements, and the notes to those statements, included in the Company's Form 10-K filed with the SEC on November 24, 2020. The Condensed Consolidated Balance Sheet as of October 2, 2020 was derived from audited financial statements which have been prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP"). Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. In the opinion of the Company, the statements include all adjustments, which are of a normal, recurring nature, required for a fair presentation for the periods presented. The results of operations for interim periods are not necessarily indicative of the results for a full year, due to the seasonality of some of the Company's business activities, the impact of the COVID-19 pandemic ("COVID-19") and the possibility of changes in general economic conditions.The condensed consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling financial interest is maintained. All intercompany transactions and accounts have been eliminated.
New Accounting Standard Updates	New Accounting Standards Updates Adopted Standards In December 2019, the Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") which simplifies the accounting for income taxes and clarifies and amends existing income tax guidance. Impacted areas include intraperiod tax allocations, interim period taxes, deferred tax liabilities with outside basis differences, franchise taxes and transactions which result in the "step-up" of goodwill. The Company early adopted this guidance in the first quarter of fiscal 2021. The adoption of this guidance did not have a material impact on the condensed consolidated financial statements. In November 2019, the FASB issued an ASU which provides clarification and improvements to existing guidance related to the credit losses on financial instruments standard. The guidance was effective for the Company in the first quarter of fiscal 2021. The adoption of this guidance did not have a material impact on the condensed consolidated financial statements. In May 2019, the FASB issued an ASU which provides the option to irrevocably elect to apply the fair value measurement option on an instrument-by-instrument basis for certain financial instruments within the scope of the credit losses on financial instruments standard. The guidance was effective for the Company in the first quarter of fiscal 2021. The adoption of this guidance did not have a material impact on the condensed consolidated financial statements. In April 2019, the FASB issued an ASU which provides clarification, error corrections and improvements to existing guidance related to the credit losses on financial instruments ASU issued in June 2016, the derivatives and hedging ASU issued in August 2017 and the financial instruments ASU issued in January 2016. The Company adopted the guidance related to the financial instruments ASU and the derivatives and hedging ASU in prior fiscal years, which did not have a material impact on the condensed consolidated financial statements. The guidance related to the credit losses on financial instruments ASU was effective for the Company in the first quarter of fiscal 2021, which did not have a material impact on the condensed consolidated financial statements. In August 2018, the FASB issued an ASU which adds, modifies and removes several disclosure requirements related to fair value measurements. The guidance was effective for the Company in the first quarter of fiscal 2021, which did not have a material impact on the condensed consolidated financial statements. In June 2016, the FASB issued an ASU to require entities to account for expected credit losses on financial instruments including trade receivables. The expected credit loss model replaced the incurred credit loss model, that generally required a loss to be incurred before it was recognized. The forward-looking credit loss model requires the Company to consider historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount in estimating credit losses. The amended guidance requires financial assets that are measured at amortized cost be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of financial assets. The Company adopted this guidance on October 3, 2020 (the first date of fiscal 2021) using a modified retrospective approach. This approach allows the new standard to be applied retrospectively through a cumulative-effect adjustment to retained earnings recognized upon adoption. The adoption of this guidance did not have a material impact on the condensed consolidated financial statements. Standards Not Yet Adopted (from most to least recent date of issuance) In January 2021, the FASB issued an ASU which clarifies certain optional expedients and exceptions for contract modifications and hedge accounting that may apply to derivatives that are affected by the discontinuance of LIBOR and the reference rate reform standard. The Company may adopt this guidance through December 2022 if the remaining amendment to the reference rate reform standard is adopted. The Company is currently evaluating the impact of this standard. In March 2020, the FASB issued an ASU which provides optional expedients that may be adopted and applied through December 2022 to assist with the discontinuance of LIBOR. The expedients allow companies to ease the potential accounting burden when modifying contracts and hedging relationships that use LIBOR as a reference rate, if certain criteria are met. During fiscal 2020, the Company adopted the optional expedient to assert probability of forecasted hedged transactions occurring on its interest rate swap derivative contracts regardless of any expected contract modifications related to reference rate reform. Other optional expedients related to hedging relationships may be contemplated in the future resulting from reference rate reform. The Company reviewed its portfolio of debt agreements, lease agreements and other contracts and determined that only its debt agreements will be impacted by this standard, as the lease agreements and other contracts do not use LIBOR as a reference rate. The Company is currently evaluating the impact of the remaining amendment of this standard. In January 2020, the FASB issued an ASU which provides clarification and improvements to existing guidance related to accounting for certain equity securities upon the application or discontinuation of equity method accounting and the measurement of forward contracts and purchased options on certain securities. The guidance is effective for the Company in the first quarter of fiscal 2022 and early adoption is permitted. The Company is currently evaluating the impact of this standard. In August 2018, the FASB issued an ASU which adds, modifies and removes several disclosure requirements related to defined benefit pension plans. The guidance is effective for the Company in the first quarter of fiscal 2022 and early adoption is permitted. The Company is currently evaluating the impact of this standard.
Comprehensive Income (Loss)	Comprehensive Income (Loss)Comprehensive income (loss) includes all changes to stockholders' equity during a period, except those resulting from investments by and distributions to stockholders. Components of comprehensive income (loss) include net income (loss), changes in foreign currency translation adjustments (net of tax), pension plan adjustments (net of tax), changes in the fair value of cash flow hedges (net of tax) and changes to the share of any equity investees' comprehensive income (loss) (net of tax).
Currency Translation	Currency TranslationBeginning in fiscal 2018, Argentina was determined to have a highly inflationary economy. As a result, the Company remeasures the financial statements of Argentina's operations in accordance with the accounting guidance for highly inflationary economies. The impact of foreign currency transaction losses for Argentina during the three and nine month periods of both fiscal 2021 and 2020 were immaterial to the condensed consolidated financial statements.
Current Assets	Current AssetsThe Company insures portions of its general liability, automobile liability and workers’ compensation risks through a wholly owned captive insurance subsidiary (the "Captive"), to enhance its risk financing strategies. The Captive is subject to regulations within its domicile of Bermuda, including regulations established by the Bermuda Monetary Authority (the "BMA") relating to levels of liquidity and solvency as such concepts are defined by the BMA. The Captive was in compliance with these regulations as of July 2, 2021. These regulations may have the effect of limiting the Company's ability to access certain cash and cash equivalents held by the Captive for uses other than for the payment of its general liability, automobile liability and workers' compensation claims and related Captive costs.
Other Assets	Other AssetsOther assets consist primarily of costs to obtain or fulfill contracts, including rental merchandise in-service, long-term receivables, investments in 50% or less owned entities, computer software costs and employee sales commissions. For investments in 50% or less owned entities, other than those accounted for under the equity method of accounting, the Company measures these investments at cost, less any impairment and adjusted for changes in fair value resulting from observable price changes for an identical or a similar investment of the same issuer due to the lack of readily available fair values related to those investments.
Other Current and Noncurrent Liabilities	Other Current and Noncurrent Liabilities The Company is self-insured for certain obligations related to its employee health care benefit programs as well as for certain risks retained under its general liability, automobile liability and workers’ compensation liability programs.

Fair Value of Financial Instruments	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities recorded at fair value are classified based upon the level of judgment associated with the inputs used to measure their fair value. The hierarchical levels related to the subjectivity of the valuation inputs are defined as follows: • Level 1—inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets • Level 2—inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument • Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement Recurring Fair Value MeasurementsThe Company's financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, borrowings and derivatives. Management believes that the carrying value of cash and cash equivalents, accounts receivable and accounts payable are representative of their respective fair values. In conjunction with the fair value measurement of the derivative instruments, the Company made an accounting policy election to measure the credit risk of its derivative instruments that are subject to master netting agreements on a net basis by counterparty portfolio, as the gross values would not be materially different.
