Shopping is a part of OUR daily life. There are people who hate going shopping. They make a list of what they need and run through STORES buying the NEEDED things. But there are people who go from store to store looking for goods of THE BEST quality and THE LOWEST price. They worry about the time they spend shopping.
The methods of shopping may vary. It may be a self-service shop where a 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, a shop-assistant helps a customer to find what he wants.
