@CSB Well w/an old fridge you'd use the trays. Then they started adding water & ice in the door and that plumbing led to an automatic ice maker in the freezer. So now you don't care if it takes 2 hours to make ice cubes because the machine constantly makes ice cubes to keep a big bin full in the freezer so you always have more than you need available. And if you need a lot for a party you just go to the nearest gas station and there's a refrigerator there full of 10 Lb bags of ice sold cheap.
