Remember the opening scene in Reservoir Dogs where the criminals meet in a diner, and Steve Buscemi refuses to throw in a buck to the waitress who's been serving the gang coffee as they plot a jewelry store heist. "I don't tip because society says I have to," Buscemi says. "All right, if someone deserves a tip, if they really put forth an effort, I'll give them something a little something extra. But this tipping automatically, it's for the birds. As far as I'm concerned, they're just doing their job."

That must be Tiger Woods's favorite movie. According to an item in Sunday's New York Post, when Woods hits Las Vegas he likes to spend, but not on tipping waiters and waitresses.

"Whenever Tiger was in Las Vegas, there was a woman who would hang out with his group, sort of as a local guide," says our source. "They would have a great time but Tiger never tips. Ever. She had to stop going out with him because it would cost her three or four hundred bucks every time they went out, since she had to keep tipping for him. Even though he paid the bill, people knew her, so [to not leave a gratuity] would reflect badly on her."

Woods's alleged tightwad ways also have landed him on Glamorati.com's list of 34 Notoriously Bad Celebrity Tippers (he's No. 23, right after Britney Spears), although the web site adds that Woods's excuse is that he doesn't carry cash.

Man, you've got to be really rich to get away with that one.
