Please fire me. I had a customer threaten to kill me and said I was “so lucky she wasn’t knocking me out right now”. Oh, and called us fat cows. All because when I finished serving her, I said “see ya, I finished my shift” to my supervisor and she thought we were talking about her.

She waited outside my shop for 15 minutes for me so I couldn’t leave the store and have had 3 panic attacks today because of it.
