A restaurant check, also known as a bill or TAB, is the document presented to a customer at the end of a meal in a restaurant. It typically includes the items ordered, the prices of each item, and the total amount due. The term 'TAB' is derived from the word 'TABULATE, ' which means to calculate or record. A CHIT is a voucher or receipt that is used to pay for goods or services. It is usually issued by the restaurant and is signed by the customer to acknowledge payment.
