I believe that what was noteworthy here, was that Foley's Downtown was the first departments store of its kind.
Designed by Raymond Lowe, it had a tunnel or backstage area that surrounded each floor. The idea was that much like Disneyland which is supplied through underground corridors, merchandise, meaning products being stocked and some goods sold, would not go through the normal customer entrances and exits. They would come in through the loading docs, up to the appropriate floor, and then around the floor in the tunnels poping out only when they reached the destination department. The newsreel seems to be featuring the state of the art shopping experience at Foley's including showing purchases being made, the packages then being dropped down a chute, eventually making it to the shipping department for home delivery OR being sent to the parking garage across the street where they would be placed in your car when you departed. It really was most civilized.
