mm, coffee... i think there's something social, familiar about it. we used to meet at the bar and now we meet at the 'bou. (coffee shop all my AA kiddos hang out at.) we tell newcomers that if they're looking for a place to go for some fellowship, we'll all be drinking coffee up there. it's cheap, maybe 2 bucks for a large coffee. refills are free. no one gets beat up in line for coffee.
in the winter it warms our hands in the parking lot as we chatter away before a meeting.
and, it doesn't get you drunk. reason enough for me.
