Once I said to a coworker, "Why are you acting like such a selfish bitch?" Okay, maybe I shouted it within earshot of her customers. She burst into tears and ran off the floor. (This is restaurant speak for leaving the public serving area.) Management had to service her tables for a while before she was able to regain her composure.
It was New Year's Eve.
At the end of my shift, the owner wished to speak to me. I was given a warning and told that calling another employee a bitch was grounds for termination. I explained what had led up to my outburst (owner then realized how tame the word bitch was in this situation) and pointed out that I hadn't called her a bitch, I had only questioned why her behaviour resembled that of a bitch.
The owner smiled and even stifled a laugh and tore up the written warning.
Now, I can't even remember the bitch's name.
