Have you ever worked behind a bar? How did you find it?

I have a trial this Saturday in a place called the Club Bar in Dundee. Anybody know it (log shot, I know)? I have no idea what kind of place it is (I handed out loads of CVs and can't remember most of the places).

But I'm really not enjoying working at the cinema I'm at currently and I'm hoping this'll be better. But I've never worked in a pub before and I imagine I won't be able to pull a decent pint.
