Senior Discount
One old guy would order a senior coffee everyday. Once he realized I was working the booth at his regular time, he wouldn’t even say what he wanted. This was lunch rush too. He would also grab the window and open it just to throw his change at me. I started locking it.
I wouldn’t even open it to answer him, so he’d go up thinking he was getting free coffee, just for my manager to explain how drive thru works. After a week, he stopped showing up. Story credit: Reddit / delainerae
