I attended Fort Walton Beach High School in Fort Walton Beach Florida from 1984 to 1986 (the year I graduated). One day, a few friends and I decided we either didn't like the lunches we brought, or what the cafeteria was serving, so we ordered a pizza.
Because they delivered.
We waited at the front entrance of the school for the delivery guy. After he came and we paid, and after he left the parking lot monitors drove up and told us this was basically forbidden, but if we gave them each a slice they'd let us break the rules just that once. So we "bought them off" for 2 slices of pizza.
We ate it in the cafeteria.
Best school lunch I ever had.
