“...inside the crowded LQ nightclub...”
My state (NM) allows open carry, and the CCW license requirements seem pretty reasonable to me. But even here, you can’t take your concealed handgun into a place where alcohol is consumed. I’ve heard people say that is an unreasonable restriction, but personally I’m OK with it.
Ironically, in NY if you have a carry license you can carry in bars, with no BAC limit.
