Same here. I worked as a waiter for about two months....I absolutely hated it. I can't stand kissing ***.
I got the opportunity to jump behind the bar after working as a doorman for a while, and found it to be a much better situation for me. I could treat the customers as they treated me, without any repercussion (which was often pretty poorly, as I typically worked some pretty rowdy dumps). I didn't instigate, but I didn't have to sit there and take verbal or physical abuse.
Stressful job if you work dive bars...people can hold some serious grudges. Death threats, destruction of personal property, getting off at 4 am, etc.. get pretty old after a while.
...but all in all, bar tending is the way to go.
