I'm a bartender. I used to enjoy a few drinks towards the end of a shift. Now I do not. I realized my drinking was a way to "deal" with the drunks, which is clearly counter-productive. Now I find myself "cutting people off" much more frequently and enjoying only my diet coke. It's still annoying to watch them act foolish, but I use their actions to keep me focused on the person I want to be and not the person I was.
