Look here's my take on tipping, do it if you want, but if you play this game as a business there is no need to tip as if its a service industry. Its not for a pro or those that try to play like one. Its business and the dealer is not part of a leisure expense like dining out or something similar. I am there to extract money and I don't care one bit about who flips the cards for me. Now of course its been talked about how overtipping allows certain courtesies, and on the rare occasion that may be true, but it also can lead to a collusion charge so the benefit is SEVERELY overstated.
I will give an example of how it works much better just the opposite. I buy in at this table one time at what I have deemed to be a very beatable dealer. I buy in for a certain amount and within 30 mins I have 5 times my buy in sitting in front of me. I have tipped nothing to this point and its steaming the dealer and I love it. One other player sits at my table and remarks at what looks to be my good fortune. The dealer can't hold back and blurts out, yeah and the SOB hasn't tipped a nickel. Heres my chance to test him. I push him, I say anybody can give me my cards, he's not doing anything but flipping waxed paper. Dealer is fuming, won't shut up about how Karma is a bitch and how non tipping will do me in. Im laughing in his face, because the madder he gets, the weaker he gets in his dealing. The more I dig this guy, the better it is for my game, and it doesn't cost a penny. I have nothing personal against the dealer, but he allows me to manipulate the game even more heavily in my favor with his own brand of steaming. He is just a pawn in my business and I feel no need to tip him anymore than any other may feel the need to tip a coworker. Its a case by case occurence and what may work one place may not work somwhere else. Tipping as a recreational player is probably ok for most as you are playing for fun, but overtipping is highly overated and most times unnecessary.
