I'd say instead make an aisle and cart design for the store such that the store's shopping carts would not be able to enter the self-checkout. Essentially, each shopper would be limited to what they can carry in a basket or two, with the added limitation that the checkout bagging area is only big enough for 2 baskets that cannot be removed once you start.
