I would never tip a vegas dealer. That seems just dumb. They get paid a certain amount by the casino, if they don't like it they can get a different higher paying job. I don't get tipped for doing my job. I hate how everytime I go to vegas everyone is looking for a handout. In every other city I have been to, the cab drivers are greatful for a normal tip. In vegas I get yelled at if its not at least $5. Ridiculous. We need to reign in this overtipping. They get used to it and then come to expect it. If a dealer is cool and has a good personality, makes you laugh, go ahead and tip him, but if he's just doing his job, F him.
