I had a guy call me a terrorist, I am middle eastern.
We had a buy 2 get one free sale on pre owned games. He wanted to buy the two cheaper games and get the expensive one free. When informed that's not how it works, he flipped out. We had to call security in the mall we were in to get him to leave. He called corporate ad corporate told us he was documented so any negative reviews on the next few weeks would be flagged. My manager stood up for me that day, I miss that guy.
We also had a fire break out in the backroom. Got rid of a lot of old inventory. Happened on Halloween. We were closed for a few days to clean and stuff. I used a fire extinguisher that day. First time ever.
