Having done it a couple of times, I can say that the key to a successful drink-around-the-world tour is to take your time, eat with at least every other drink, and drink plenty of water in addition to whatever adult beverages you choose to sample. No need for anyone to get sloppy or obnoxious if you do it that way.
I am a part time bartender and also have run several successful beer tasting tours in the Philly area - pretty much every bar we visit is always glad to see our tour come back because they know we aren't going to be any trouble.
