Dunce Dunn Bros Coffee is celebrating their newest location at the University of Minnesota by offering a coupon for a free medium coffee. For the price of a small.

What? No, it’s either free, or it’s the price of a small. Not difficult. Patrons attempting to redeem the offer need to bring in the coupon, and possibly a dictionary.
