Women and Tipping

I've spoken with waiters, waitresses and cab drivers. They have all told me that men tip way better than women. The overwhelming number of tips in the hospitality sector comes from men. I know many New York City cab drivers that will avoid a woman to pick up a man because of this fact. The only time I've ever seen a woman tip well is if that woman was, at one time or another, a waitress herself.

Which of the sexes are greedy, stingy and selfish? Remember that when a female calls you cheap for not buying her the most expensive meal and wine on your first date.
