Weigh each customer/cart going in and going out. Make sure the weight of each item is a prime number. And... remove any restrooms from the store.

2+3=5. In general, the weight idea is impossible. For any two items, you can find the LCM in units of the precision of the scale, and then you won't know if they got LCM/a of one or LCM/b of the other.
