Sonny, couldn't agree with you more on the no-class not going to dinner on the last day so as not to have to tip. Even if you weren't totally happy with their service, they still brought you your food and took away your garbage. Have a spine and tell them you weren't happy, and WHY. It was a vacation, not a 5-star restaurant!! I always tip over the pre-paid for our waiter and assistant, and more so for our cabin attendant; I'm a basic slob, so they more than earn some extra..............
