Well, ya gotta tip something or you are an ass. Vegas is a tip oriented city. I think $25 is absoute bare minimum and somewhere $30-40 would be "good", and $50 would be "great". We were playing shorthanded for awhile and the pots and tips had been really small so felt like doing a nice thing so chose "great". Plus the three bet on the river got me an extra $18 that was essentially stealing.......But it's all a matter of opinion, no right answer, how much would you have tipped?
