Banking On It Being An Actual Bank, Part 2

I’m working in a card store. A man comes up with a “Happy 50th Birthday” card. 

Customer: “I’m going to give you $100, and I want a really crisp $50 back. It’s for my friend’s birthday.”

Me: “Oh, sorry, I don’t think we have any $50s, let alone crisp ones.”

Customer: “Why not?”

Me: *As politely as possible* “Um, well, we’re not a bank, sir.”

Customer: *Huffs* “Fine, then go to the bank, but hurry up.”

Me: “Uh, sorry, sir, but I can’t just leave; I’m the only one here.”

I think that even if I could, we don’t just go to the bank for customers!

Customer: “This is ridiculous! What am I supposed to do, then?!”

Me: “Well, you could go to the bank…”
