Story you may like: Years ago, dinner for 12, celebrating a college graduation. Nice restaurant, lousy service. $700 + tab. My father-in-law, was the host, left three 20's as the tip. As we walked out, he was in front of me and I was bringing up the rear.
Waiter approaches him, the bill folder was open, three 20's on display. Waiter says: "Sir, I think you may have made a mistake."
Without missing a beat, F-I-L, says: "You're right son, thank you very much." As he says this he picks up one of the 20's! I bet that waiter never pulled that one again.
Excellent! Imagine the nerve. How sad it is that some people wander through life without a clue. Ironically, they’re usually the most boisterous in their opinions.
