This was in small towns. So yes, there was a milk store. Which sold milk that people delivered directly from their farms. Not pasteurized. You were supposed to boil it at home.

Also a coffee store, which also bought directly from farms. And a bakery, with wood-fired ovens. Plus many other small stores.

And then, an hour away by motor vehicle, was a Walmart. Stuff was so inexpensive there that many local stores resold stuff that they bought there.
