Today, most groceries stores are too big for one person to take care of. Because of this, the customer has to find the items he or she wants by him/herself. Most often, the customer would take a shopping basket or shopping cart and put the items he or she wants to buy into the basket or cart. For some items, like meat and seafood, the customer still has to have an employee get or prepare the item. Once the customer is done shopping, he or she then brings the items to the "checkout", where a person called a cashier scans the customer's items into a cash register (or a computer as part of a point of sale system) and then takes the customer's payment. Supermarkets typically accept payment by cash, debit cards, and/or credit cards. Recently, there are so-called self-checkout systems where the customer scans the items on his or her own.
