It is insulting to call people lunatics. Clearly you don't care if you offend anyone.
When I go out on black Friday, I go with adult family members. We make a night of it. It has become a fun tradition for us. There's no lunatics and people being killed. Most people know what to expect and are ready for it. People are often friendly and talkative in line.
I spend extra time with family because of our black Friday shopping trip.
I have worked the last 4 Black Fridays, and that's what I saw. People are nice, talkative, and occasionally a little silly from lack of sleep. I have never seen anyone say or do anything mean or disrespectful. Out of all the people out shopping, you only hear a handful of negative comments. That is only a small fraction of the people out there.
