I was at a mini-convention a few years ago in San Antonio, we had a hour for lunch.
We went to the dinning room at the large hotel, we got the menu and ordered. after waiting 45 minutes and getting no food we left and had to send out to the Buckhorn Saloon for sandwiches. My wife asked are you going to leave a tip and I said "For what, bringing us a menu and a glass of water". TIP = To Insure Promptness. What do you all think?
