An Irrational Order

I work in a fast-food place near a college campus.

Customer: “I want the chicken deluxe sandwich and the uh… polynomial sauce.”

Me: “…Polynesian sauce?”

Customer: *Blinks.* “Uh… yeah. Sorry.”

Me: “Math class?”

Customer: “Yeah. Finals week.”

She looked sooooo tired, so I threw in some extra waffle fries.
