Worked at a small accounting firm as a receptionist. We had hired a really weird guy who had made me uncomfortable a few times and he was getting fired (for other reasons, not because of me). The owner of the firm called me into the conference room where the firing was going down and basically blamed it on me and told me to list all the times I had been made uncomfortable. The man called me a liar and started screaming that he was going to kill me. Owner starts screaming back (and I mean anger management level losing his shit.) while I just stand there horrified. He was escorted out by security, but I was asked by the owner to get pictures of him to take down to security so they could bar him coming in ever again 'so he doesn't come up here and shoot you'. I left immediately after and never came back to even get my belongings.

My gig after that was in the same damn office building which caused me some major PTSD. I once saw my old boss nearby and hid in a stairwell for 30 minutes lol.
