My last two shifts, I've dealt out 3 high hand bonuses, each worth between $100 and $500 for the player. This is better than average for me, but not a huge aberration.
1. 2/4 limit table. Player is familiar to me, but not quite a reg. Tips $1 on pots in the $20+ range and may or may not tip on a hand between $10-$20. (Not judging the player here, but showing his regular tipping pattern... and 2/4 pots don't typically get bigger than $40 in my room. If I were to guess ahead of time, I'd have predicted a tip of 1-2% for the bonus payout and no tip at all seems possible.
2. 1/2 NL table. Player is a reg who plays 30+ hours per week. He tips $1 on substantial pots and doesn't tip on smaller pots. Like the 2/4 player before him, I'd guess a 1-2% tip on the bonus.
3. 1/2 NL table. Player is a semi-reg who rarely tips, regardless of pot size. I've pushed him $100+ pots and received no tip, but I've also received a $5 tip from him on a hand when he sucked out on the river to win the pot. My best guess is that he'd not tip at all on the high hand bonus.
Once again, the descriptions of the players are not to promote any sort of personal agenda, but rather to illustrate what my idea of a standard* tip is for bonus payouts.
*Standard - meaning, the reality of how players actually do tip in my region, as opposed to anyone's personal belief of how players "should" tip.
I'll be happy to keep track of bonus payouts and tip amounts for a larger sample size if anyone's interested. Otherwise I'll put this topic to bed.
