There are a lot of rude stories, but one that sticks out was this...
We had these Shamrock pins with rhinestones in them that were $2 and the sales went to Children's Miracle Network.
A lady came in with one after St. Patrick's Day and wanted a refund for it because one of the stones fell out. We had plain ones left we would have given her, but she wanted none of that.
My coworker that took care of her said, "That money goes to a charity, we don't profit off of it."
Douchebag: "Well it broke."
CW: "So you want us to take money out of the fund for the SICK CHILDREN and give it back to you?"
DB: "Well, yeah, it broke."
So a manager had to come up, go up to our cash office, get $2 out of the CMN envelope for her, because she's an evil bitch who doesn't understand $2 pins don't last forever...
The lady behind her put $5 in and, "Couldn't understand why some people are so selfish."
So not the rudest person ever, but seriously? Taking money from the sick kids because your pin broke? Bitch.
