What would be the busiest hours at a diner in a midsize town in Indiana during the 1950s? I know vaguely – morning, lunchtime, dinnertime – but typically what hours specifically would these be? What would be the least-busy times?
Here's an area-specific question:
When were the pole-shaped pay-telephones in Harvard Square (the ones by the Pit) installed? I've tried Googling various combinations of "Harvard Square" "pit" "telephone", but most of what I turn up just says that the pay phones exist, nothing about when they arrived.
