Back in the day, when I was working out regularly in martial arts, we would always go to a rough bar and drink beer after the workout. Never had any problems.
One time I joked with my buddies saying, with the shape were in right now, we should wear cups and carry mouth guards in this place, in case we get in a fight. We could make a big point of letting the rednecks see us putting in mouth guards for intimidation purposes.
Of course that was then (20 yrs ago) and this is now. That would have been a bad idea, not knowing who might have had a gun or something.
I know one thing, if I did get in a fight I'd feel a lot better wearing a cup and mouth guard when it happened.
