People do shopping almost every day. When people want to buy something, they go to shops where various goods are sold. Through the shop-window we can see what is sold in this or that shop. Big supermarkets self-service shop. Customers can buy all the necessary foodstuffs there: bead, milk, meat, fish, grocery, sausages, sweets, vegetables and fruit. When customers come into shop, they take a food backed and choose the products they want to buy. When they put everything they want into the basket they come up to the cashier’s desk. There is a computer with a laser scanner that reads and sums up the prices on packed goods at the cashier’s desk. The saleswoman tells how much to pay. The customers pay the money and leave the shop.

At the grocer’s you can buy sugar, tea, coffee, salt, pepper, ham, bacon, sausages, frankfurters and so on. Bread is sold at the baker’s, meat at the butcher’s. We go to the greengrocer’s for vegetables and fruit. Cakes and sweets are sold at the confectioner’s. When we want to buy clothes, we go to men’s and ladies clothes shop. We buy boots and shoes at the footwear shop. We buy jewelry at the jeweler’s. We buy books at the bookseller’s.
