The age check is actually a legal requirement - the bigger challenge was actually getting the delivery person to consistently do it!

Oh yeah but I mean the delivery guys are often underage themselves. It might present a legal issue. And indeed, they don't tend to be too precise, especially if you just hand them a nice tip :) Much less likely to happen in a physical store or bar.

So I could imagine the local law enforcement wouldn't have too much confidence in the process, that's what I meant :)
