Its been a few years since i worked in fast food/drive thru. But the highlight of my time there was when a car refused to take thier receipt. Literally threw it back at me when i gave them thier drink + reciept. (reciepts are given to all cars incase of an order mix up)

Walked over to the other window, and put the reciept in the bag with thier food.

No no no, you can nerd snipe me THIS time (save to solve on my lunch break)
