i tip 30-50% depending on where i am.

if its a $15 meal, like at Taco Mac, i leave $10. My bill was $27 at Strip on Friday night an i gave him $23 to make it an even $50(he was really good and took 10% off because we were going to Cirque Du Soleil)

I had a $187 tab at TAP for a friends Bday and i left him $40.

I tip big, just because i know how crappy it is to be a server, and hopefully that makes their night. I have been blessed and i believe what comes around goes around.

IF the service is absolutely horrible, which maybe happens MAYBE once a year to me, ill leave 15%
