Modern Drunkard Magazine advises us that it is important not to have too many rules:

It’s A Party, Not a Penitentiary

Along with inviting a large group of people into your home comes the natural proclivity to lay down some rules. Resist this urge with all your might. Forcing your guests to use coasters will make tomorrow’s clean-up slightly easier, but it may also trigger an Uptight Principle/Juvenile Delinquent vibe. A party is about extending freedoms, not curtailing them. Do not enforce any rules that are not enforced in a bar. Do not guilt your friends off a perfectly good bar stool so you may lord over them.

But Club 216 isn't the only place with a lot of rules in Charlottesville. Check out this sign posted on the door at Rapture, a decent restaurant that has a healthy bar scene. It's pretty clear that they are aimed at the local black community, and they are so vague that they could easily be selectively enforced against the unwanted.
