Grocery Store Kiosk

Wouldn't it be cool if you could go into a grocery store, sit down at a kiosk, order all your groceries and have them spit out onto a conveyor belt?  If you accessed the groceries with a machine you could store a lot more in a lot smaller space.  The kiosk would be easier for busy people and mothers with kids.  You could cut down on the people needed to run the store and save on labor costs.
