"Here's that stapler with mustard you ordered..."

I ordered two parfaits in the drive-through.  When I got up to the window, the clerk started to hand me coffee.  I told her I'd actually ordered two parfaits.  She returned with a sausage and egg biscuit.  I explained again that I'd ordered two parfaits.  The third time, I received the right food.  I was still slightly disappointed, though, as I was curious to know what I might have received incorrectly a third time--a tape dispenser, perhaps, or maybe a socket wrench or a llama.
