Setting the trees on fire was actually part one of his cunning plan.
An unnamed 28-year-old Traverse City, Michigan man is facing charges of arson, assault, and breaking and entering into a vehicle after going batshit insane upon assuming he was fired. Via UpNorthLive, his manager apparently asked him to leave work for “employee-related issues” and because he was causing some sort of disturbance. The man apparently assumed he was being fired (it’s implied this wasn’t the case at the time, although I think we can say with some confidence that it is now), and so he took the eminently reasonable step of lighting a bunch of trees behind the KFC on fire, because, uh, sure, that’s a thing you could do. He then left, only to come back a couple hours later and shove his manager (hence the assault charge).
