For what it's worth, I'd suggest doing your RSA (Responsible Service of Alcohol), RCG (Responsible Conduct Gaming), Senior First Aid, Bar Service course and getting a taxi drivers licence (ground).
People always want to drink and they'll always need someone to drive 'em home. It doesn't matter what company you work for..there's usually a pub somewhere close to where you're working (if you need a bit of extra cash) or a taxi that's looking for another driver to help out.
might even take that advice myself!!
