Twice I have encounters, one in a regular grocery store, one at a convenience market, with this kind of nut, hopped up on who knows what. Both times I slipped away as the nut was moving closer and ranting louder and louder. The convenience market guy was on 911 as I ran out the door. ‘Please come quickly’, he said, ‘I don’t want to have to use gun.’ Convenience store guy was a Korean.
egads- not cool- thankfully nothing happened- hopefully the clerk didn’t have to resort to gun use- but thankfully he had it just incase- better to have it and not need it than to need it and not have it=-
