What?

I travel quite a bit. Everywhere I go one of the most basic rules is that sooner or later, I'll need a beer. The rules for getting served smoothly in pubs and bars, though, vary wildly throughout the world. My plan here is to summarise the standard rules of bar etiquette in all the countries I can find rules for, so others can avoid making idiots of themselves when visiting strange countries... when all you really want is a pint.
