Объяснение:

It may be a self-service shop where the customer goes from counter to counter selecting and putting into a basket what he wishes to buy. Then he takes the basket to the check-out counter, where the prices of the purchases are added up. If it is not a self-service shop, and most small shops are not, the shop-assistant helps the customer in finding what he wants. You pay money to the cashier and he gives you back the change.
