If a brewer were to keep a donation jar near his kegs (i.e. tip jar), would this be strictly legal in the United States? Sales of homebrew are prohibited, and this website states that requiring a cover charge for a party where homebrew was served would also be illegal. But, since a dontation/tip is not required to drink the beer, would this also be prohibited?
This question is really in two parts:
1) Is it strictly legal to have a tip jar?
2) Practically speaking, does anyone ever actually get in trouble for this?
I understand that laws will vary state-to-state. I am interested in any specific information you have, regardless of state.
