Back in the 1920’s, if you lived in a warmer climate, ice was hard to find. In fact, if you lived your whole life by the equator you would probably never even see a piece of ice and wonder what all the fuss was about. Even if you didn’t live on the equator but you wanted ice to cool drinks or to keep food cold, you would have to buy it from a delivery service which imported it in large chunks, or alternatively from an industrial sized refrigeration plant.
