So you don't tip the dealer if you win a pot less than $50? Wow. I mean, I appreciate your honesty, but just, wow. Ever think about tossing them a couple bucks when they change shifts then? I don't consider it a tip for good cards, just for their efforts doing a relatively monotonous job for hours on end that pays shit. The tip comes from the player that wins the pot because, well, they won the pot, lol.
I do tip dealers when they push out... in particular, good dealers. I just don't tend to tip much just because I made a tough call, or because I overbet causing everyone else to fold. But when it's going to the river, I'm usually tipping. If it's a flop and fold hand, the pot tends to be small.
Say you get a $30 pot. That's SB ($1), BB ($3), one player limps and eventually folds ($3), a bet ($12) and a call ($12) ($31 total, but let's not split hairs). Flop comes out, you bet and everyone folds. House pulls $3 for the rake, and another buck for some crazy jackpot. That's 13% of my winnings, gone. Now I'm expected to hand over even more of it?
At least once we hit $50, the rake has been capped. Giving up another buck is cheap but fair. If the hand is a monster, I have no issue handing over a $5 chip, because the house rake is now well below 10%.
I don't advocate others do the same, of course. As I said, I know in a cash game I'm a shitty tipper. Tournaments I tip well, as I do valets, waiters, and the pizza guy. Cash games just bring out the worst in me (hence my preference toward tourneys).
