Great idea!
I like the coffee, hot chocolate or water idea
When i was much younger i was a volunteer making donuts for over 80,000 people at Dodger stadium in 1969, shows my age, i still have the hot oil burn blisters on my hands.
Rows upon rows of industrial sized deep friers, donut dough mixers, icing trays, it can be done.
Fill the soul, satisfy the tummy i say.
