Barstool

To the OP: I agree with willtravel on this. I tip no less than 15% for a meal, if the service was average. I'll go up significantly if the service justified it. At more expensive dinners, I'll tip 20% or more usually because the service matches the food. At a bar, I tip $1 per drink, or if I'm ordering some beers, I'll give $1 or $2 to the barkeep. For other things, like haircuts, I usually leave $2 on a $10 cut (that's what, 20%?) For taxis, I pay cab-fare + $5-$10 depending on how quick, rude, direct, or helpful the cabbie was. Everything else I play by ear.
