Lauxa, are the owners of the club aware of the incident? I would speak to the owner and see how willing they would be in fostering an zero-tolerance atmosphere for this sort of behaviour. I personally wouldn't kick someone (or in this case a group) out the first time they behaved in such a fashion. I'd attempt to talk to them and warn then about their behaviour. And then kick them out if they refuse to cooperate.
If the owners will not cooperate, I'd just move on with my life and find a new place to hang out in.
