It was a penny, but it was your penny.

At the very least, the little bitch should've said "Sir I'm out of pennies, would you like me to go get one?"

At that point you either say yes or no. I'd probably say no because it's a penny and I'm not a jew.

I'd say you have justification to be a little annoyed, but who doesn't now a days when dealing with fast food workers lmao.
