After several years working bar up and down the country in  my younger years………….. definately mind my own business in a shtf scenario even now UNLESS it’s someone being robbed or I suspect sexual assault.

I’ve seen a guy hit a girl someone got involved and both guy and girl turned on him, I’ve seen 2 chaps start fighting and when people have tried to break it up both turn on them, people are the most dangerous animals I know.

If at first you don't succeed, excessive force is usually the answer.
