I know, what a rowdy lot!
My personal experience is that there have been a lot fewer fights and other types of antisocial behavior in strip clubs than in non-stripping bars that I have been in, or at the parties that I went to in college and law school. I think that the reason for that is clear: very few "amateur" women are present, and of those that are in attendance, very few are available to be picked up. Most of the fights that I have seen in bars and parties have resulted from guys fighting over girls which, by and large, doesn't happen in strip clubs. Guys in strip clubs are either there by themselves, and have no desire for interaction with the other patrons, or are there with buddies, and aren't going to raise hell.
Think about it--if there are no women to compete over, what are men going to fight about?
There is also the factor that some of the guys in strip clubs don't necessarily want their presence to become common knowledge in the wider community, and are going to try to keep a low profile.
In fact, the only violent act I ever witnessed in a strip club was a couple of years ago, when an off-duty cop punched a guy in a wheelchair. I have seen guys try to get ugly about not getting served, or get in mathematical arguments with dancers about the number of dances they have had. But the bouncers handled these very discreetly and efficiently.
I have always been impressed with the fact that I have been able to go into a fairly wide range of strip clubs dressed professionally, and never gotten any shit about it. The only time that other patrons in a strip club have given me any problems was a couple of months ago, when a group of about 5-6 young (early 20s) guys started ragging on me for taking a couple of trips into VIP. When getting me a new drink, one of the waitresses told me that they apparently were tapped out, because they hadn't tipped or gotten drinks in about 1 1/2 hours, and they were about to be asked to leave the club.
