This seems like a perfect Sunday topic and was reminded of this pet peeve I've mine this morning while picking up a Bismark from QT. I get to the register, and the cashier asked if I had a regular or big donut in the bag. huh? It is a Bismark, it is a not a donut. Donuts have holes in the middle of them. That why we have donut holes. Anything that is not a donut, is a roll. (BTW....QT lists this correctly as "rolls" on their signage, so this was a cashier thing, not QT's). I noticed this awhile ago in our cafeteria at work. In the area they keep the donuts and rolls, they posted a sign with the prices of donut and "big donuts". I'm curious now. Is this just a central Iowa thing or does this odd confusion exist elsewhere as well? I grew up in Minneapolis/northern Iowa and never came across this until locating to central Iowa.
