My favorite was to dress nice, go to a nice rest. and be seated for a party of 2, with your "date" to be on the way. Tell the waiter that you will wait for your date to order, even drinks. Eat the rolls, drink the water, steal the crackers and the butter, and after an hour or so, look like you are going to cry and tell the waitress you have been stood up. Walk out full, with a snack for later, and they never even mind that you don't tip them since you are so tore up about being stood up.
