Wanting a receipt and requiring a signature on it are entirely different, as in "quantum leap." I do 20-40 valet parking shops per month and would never do one with that requirement. Also, several clients have decided to direct that we NOT ask for a receipt because:
a. The valets were IDing the shoppers due to being cash customers who require a receipt, and
b. the client can verify the visit by checking the ticket number.
