SUPER Supermarket (Feb, 1947)
Painless marketing has arrived for the housewives of Ridge wood, N. J., where the Grand Union store is trying out a spectacular new self-service gadget called Food-O-Mat. In simplest terms, Food-O-Mat works on the principle of the familiar paper-cup dispenser: take out one item, and another slides or rolls down an inclined metal ramp to take its place. There’s a return slot below each display for the use of congenital mind-changers.
Housewives applaud Food-O-Mat’s time- and step-saving features. Clerks approve the ease with which stock can be kept shipshape, with no need for overtime display work. Owners are happy over the fact that they sell five times as much per square foot as the conventional grocery.
