"I'm sorry, I cannot break a $100, do you have another form of payment?" "Nah it's fine" -continues to try and hand me the 100. I assume he didn't hear/understand the question so I repeat. He gets annoyed and says "I HEARD YOU THE FIRST TIME. JUST TAKE IT." We went around and around for a couple of minutes before my manager came over and said "Sir, we do not have the money to break that for a ten dollar order. There is a bank across the street, and we will hold your food for you"
