Some people like to drink. A man often processes alcohol quite well, and can have a beer (or two) and be safe to ride or drive after around an hour. Someone who doesn't metabolize alcohol as well (like most women, and some men) can't do that. A 2 hour wait usually will be fine, or just skip the alcohol.

I wouldn't do a "tour de tavern" or something like that. Not cause I don't like beer, because I do. My body doesn't handle alcohol well, and I do need a 2 hour recovery after a beer (or to drink my beer veeeeeery slowly). Sometimes I need more than that, especially if the beer is a pretty stiff style. So unless the places are prepared to serve me tasting amounts only, I can't do that kind of ride. But I'm not going to be upset if someone with a better alcohol metabolism has fun with a ride like that. Little envious maybe
