Great thread.. As biminiblue says 'Alcohol isn't going anywhere'.
I'm a business owner too, of an accommodation place that has a bar. I'm around booze all day long. I do the day shift so I can get all the admin stuff done while guests are out and about - but I still do serve drinks in the day if people come in. I stay away in the evenings when the bar gets busy though.
I had jobs like yours all through my twenties. Party time. If you're anything like me the fast pace of those jobs is part of the fun too. I would have died of boredom at a retail job or something else commonly held by people in their twenties. If you still want to work with people doing something fast, how about swapping nights for mornings? Brush up on your barista skills, and make coffee. It's a good time, fast paced, and a fun (coffee obsessed) crowd to work with. I agree with the others that suggest a different job would help.
