Karma and Poker Tournament Dealers

Why do you want to tip poker dealers well? A dealer who knows you tip well will use their karma to help bring you a card over someone else who may not tip as well. This may not work at all, but from my years of dealing and playing, I have learned that there is alot of karma in poker.
In a lot of B&M casinos the dealers do not share in tournament prize pools, nor are there any monies taken out of the buy ins for the dealers. They make their measily hourly wage and hope for tips. I try to make this well known so that the dealers can hopefully make more than the usual 3-5 bucks a down with the smaller buy-in tournaments that are so common nowadays.
I split a tournament with with 3 other players in a B&M Casino today. (They were generous and gave me 2nd place money in the split due to my solid chip lead.) When I tipped the dealers 10% of my net win, I made sure the other players would tip well too.
The morale of this: Ask the tournament director or the dealers how much money is taken from the buy-in or prize pool for them. If they earn 3% of the prize pool (1% floor/2%dealers) you should tip 5% of your net win. Adjust your tip according to over-all dealer skill, professionalism, and general friendliness. (did they make you laugh or did they make alot of mistakes?) If there is no monies taken for the dealers, a 10% tip is considered nice. I have seen small buy-in tournaments ($50) where the dealers are tipped 10% and still do not make more than $4 a down. Bad karma for those dealers
