It will largely depend on where you go imo, I worked at a club for about a month and a half but quit as friday/saturday night shifts from 9pm-4am pretty much cripple any social life on weekends .. I guess it also depdnds on whether you're at school or uni, a 5 day week + this job on the weekends I doubt would be ideal, but if youve got the time to catch up with friends during the week I guess it cant hurt ..
My advice though, keep it as local as possible .. unless you're tending theres not a huge chance of 'getting hit on', and if you havent worked in the industry before chances are you'll be glassing first (pick up glasses, clean up spills etc..). Having no experience in hospitality before this job I was paid pretty low, even for the hours but as I said, itll all depend on where you go .. if you can find a place with other great employees it can be a really fun job.
