You meet only the worst people when you go out shopping during black friday.
I had to work black friday security once in the Air Force for the store on base. It's called AAFES (Army, and Air Force exchange) Navy is called NEX (Navy Exchange). We had to stop spouses and, military members from acting like total douches to each other. As soon as they saw the police, everyone was a little more cordial. Nothing worse than having to explain to your commander why you threw a retiree to the ground for some crap.
