George, to have a social drink in the uk is considered nothing more than that, the US is much more religous and reserved, dare I even say paranoid when it comes to alcohol. The only drink problem I ever had was two hands but only one mouth!
Kash360 good on you for making the effort and providing you are working at least as hard as you are playing and providing you don't get a reputation for being a bit of a piss head, you shouldn't have a problem. All the best.
