Obligatory not me but my wife. She had a co-worker that literally punched a customer, wasn’t fired. He later got into a physical altercation with another co-worker, wasn’t fired.

Then he wrapped my wife’s hair around her throat and “play choked” her. Still was not fired. Finally, he got into yet another altercation with a co-worker and pulled a gun on him, all while on the clock. Then he was fired.
