Interesting topic, I'd be curious to hear stories from others about dealers landing on their lifetime no-tip list. I have only one:
I was sitting in a 4-8 game when a middle-aged female dealer tapped into the game and started a casual conversation with a couple older regs. She said something about how she had been locked into a 15-30 game because of an error in the dealer rotation (15-30 is the biggest game in this limit-only room). The following conversation occurred:
Old lady: Well that wouldn't be so bad, you probably made bigger tips there, right?
Dealer: No, in fact I make less on that game than I do on a 3-6 or 4-8 game! I pushed a $1000 pot to that guy sitting over in seat 8 (points). Guess how much he tipped me?
Old lady: I would hope twenty dollars, at least!
Dealer (in dramatic tone): One measly buck.
Old lady is shocked at this of course, and says something to the effect of how she would have tossed it back and said "you obv need this more than me," and the dealer says she would have done this if she could. It also should be noted that this was a quiet table, and this conversation could be heard clearly by everyone there. I said nothing, but silently vowed to never tip this woman again.
She worked mostly day shifts, and I mostly came in at night, so my moment of glory didn't happen until nearly a year later. The deck hit me in the face and I won three racks in her down in an 8-16 game, and I saw her whispering to the next dealer with a disgusted look on her face as she got tapped out. I made sure to overtip the next dealer.
