One meme that is going around is that one of the Koch brothers won't tip at the country club where he buys his billionaire friends meals.
One of my habits is I go out to breakfast to meet a friend every Sunday before she goes to church. While I don't eat much, I give a minimum of a 5 buck tip, even though my meal might even be less than that (I feel that a waiter having a wage of 2.45 an hour plus tips is idiotic, so I have a 5 buck min.
For some reason, I get excellent service , all the time.
