Go to a Krispy Kreme store and order atleast 6 donuts. Leave the store and come back in about 2 mins later, skip the line and go to the front. Tell the cashier that they put the wrong donuts in the box. They will then ask you which donuts you wanted and quickly give them to you as they have waiting customers. They won't take your old food because, unlike some other food establishments, they don't like throwing it away.
