The modern supermarket is a post-WWII phenomenon. Before that, in most places, you would write up a list, go to the pharmacy, grocery, butcher, or the like, hand it to them, and they would pick out all of your items for you. Items were warehoused in the back of the store, leaving the front for displays, ads, candies, and indulgences.
