I used to work in a bar in Manchester city centre and I know exactly what you mean about the alcohol and asshole thing. I once got a large glass ashtray launched at my head for suggesting to a drunk that perhaps it might be time to call it night and when I asked a man who was squaring up to his friend if he could please take it outside he infomed me that if I didn't effing well eff off I'd get the effing beating of my effing life. Nice, very eloquent. I'd spoken to him earlier in the day before he got smashed and he was really pleasant and quiet. Some people really shouldn't drink.
