In both grade school and junior high school, I went home for lunch. In junior high school, though, since everyone could leave the building at lunchtime, the local drug stores that had lunch counters, plus the G.C. Murphy store, were mobbed at lunchtime. The high school, several blocks away had a cafeteria. Students could still leave the building but there were no nearby places to eat that I recall. I doubt students are allowed out of the building at lunchtime now.
