Ha aren't you a funny one? I was born in Vancouver and have 3 passports (Polish, Canadian, and Iranian which is pretty much useless).
Well in this case, bud, it is fairly simple.
You walk into a bar/club, you ask if they have an opening. They don't - you leave, they do - you stay and start bartending. Probably will help if you learn Polish by the time you start doing the asking.
Don't expect to make much money.
