Commitments and Contingencies Disclosure [Abstract]
Litigation and Other Contingencies	Litigation and Other Contingencies Cintas is subject to legal proceedings, insurance receipts, legal settlements and claims arising from the ordinary course of its business, including personal injury, customer contract, environmental and employment claims. In the opinion of management, the aggregate liability, if any, with respect to such ordinary course of business actions will not have a material adverse effect on the consolidated financial position, consolidated results of operations or consolidated cash flows of Cintas. Cintas is party to additional litigation not considered in the ordinary course of business, including the litigation discussed below. The Company is a defendant in a purported class action lawsuit, City of Laurel, Mississippi v. Cintas Corporation No. 2, filed on March 12, 2021. This is a contract dispute whereby plaintiffs allege that Cintas breached its contracts with participating public agencies and seek, among other things, contract-based damages in an unspecified amount. In March 2022, the District Court denied Cintas’ motion to compel arbitration, and on March 6, 2023, the Ninth Circuit Court of Appeals affirmed. Any liability in this matter is not probable nor estimable at this time. Cintas records an accrual for legal contingencies when Cintas determines that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. As of August 31, 2023 and 2022, Cintas did not accrue any additional sums in excess of its other legal contingency accruals for adverse jury verdicts arising in the ordinary course of its business. The litigation discussed above, if decided or settled adversely to Cintas, may result in liability material to Cintas' consolidated financial condition, consolidated results of operations or consolidated cash flows and could increase costs of operations on an ongoing basis. Any estimated liability relating to this proceeding is not determinable at this time. Cintas may enter into discussions regarding settlement of this and other lawsuits and may enter into settlement agreements if it believes such settlement is in the best interest of Cintas' shareholders.
