Not true... just look at all the high-profile cases of teenagers being "tried as adults" and sentenced to prison in the US.
I suspect that the AC's minimum age rule is a result of simply not wanting to have to deal with unsupervised teenagers in a lounge that's meant for adults. The nature of supervision doesn't really make a legal difference.

Bingo. They'd risk losing their alcohol license, and there are also liability concerns if they unintentionally serve alcohol to a minor (it's similar, in most if not all states, to serving alcohol to a visibly drunk person -- the person serving the alcohol becomes liable for whatever the minor does while under the influence).
