Have you ever noticed…
When I buy donuts, the counterperson picks up each donut using a 6×6 inch square of fresh tissue paper. Presumably, this is to keep from touching the donut.
Then he (or she) places the donut into a bag, or box, along with the square of tissue. Repeat for each donut.
So… if the reason for the tissue is to keep the counterperson's fingers off my donuts, why are the fingerprinted tissue squares placed in the bag? Am I missing something here?
