I had one guy who was a big shot from financial service manager who kept moving the goal posts of his order and no matter what I did he complained and I called me "a dumb fucker" and kept loudly berating me for ten minutes. I thought I was going to be scolded by my union supervisor, but she actually did the opposite and said "Don't ever let someone talk down to you like that again, if they do tell me and I'll tell them to leave. He had no right to talk to you that way."
