A Concorde-ial Response

I was working as a cashier and went to hand the customer his receipt. He waves down my receipt-holding hand and says:

Customer: “Keep it, less waste in the world.”

Me: “It’s already printed, sir.”

Customer: *Suddenly angry.* “Well make a f****** paper airplane with it, then!” *Storms off.*

I made a little Concorde! I wrote ‘F*** You Airlines’ on the side of it.
