Very seriously.
Have you seen a DD? They have donuts in trays on the wall behind the counter. They are getting cases of donuts in the morning, and they load those into the trays, and then grab them with a napkin and put them in your bag.
What possible reason could there be to not eat those? Tell me the story I should be concerned about which would make them assur. As sw33t said, pretend it is an apple–would you not buy an apple from there and eat it?
