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. Liability in this matter is not probable nor estimable at this time. However, this matter, if decided adversely to Cintas or settled, may result in liability material to Cintas’ consolidated financial condition, consolidated results of operations or consolidated cash flows.
