My temporary wife, before Galadria, had been a waitress, and made good money, but she sure had a system to tell when somebody was going to tip her well, and it worked like clockwork. She loved small parties that were all male, she would flirt with them and make 20-25%, if not more. She also said that the pretty female waitresses made much more than the waiters, especially if it was just a couple. She also had a system to tell when they weren't going to tip well or at all, but I can't post that, as it would be against the TOS.
