Quoted from boustrophedonic:then the OP became a thief and lucky not to have had the cops called.
Lol. Is this really how you think?? It's a public establishment. If they didn't want non-party guests in they need to do a better job of managing it. Calling the cops would have been an epic fail and only warranted if the OP became belligerent when asked to leave and refused. It's not the customer's responsibility to know what private events are going on at any particular location.
