A drive through moving supermarket will exist

Chicago Tribune newspaper :
There will be a drive through supermarket "Corner Grocermat". It will enable the housewife to drive around an oval arrangement of such preloaded display sections and pick out what was needed. A clerk would put the desired groceries on a moving belt which would move when the auto did, so that the purchases would wind up at the checkout counter at the same time the driver did.”
