When we want to buy something, we go to a shop. There are many kinds of shops in every town or city, but most of them have a food supermarket, a department store, men's and women's clothing stores, a grocery, a bakery and a butchery.

I like to do my shopping at big department stores and supermarkets.

They sell various goods under one roof and this is very convenient. A
department store, for example, true to its name, is composed of many
departments: ready-made clothes, fabrics, shoes, sports goods, toys, china and
glass, electric appliances, cosmetics, linen, curtains, cameras, records, etc.
You can buy everything you like there.

There are also escalators in big stores which take
customers to different floors. The things for sale are on the counters so that
they can be easily seen. In the women's clothing department you can find
dresses, costumes, blouses, skirts, coats, beautiful underwear and many other
things. In the men's clothing department you can choose suits, trousers,
overcoats, ties, etc. In the knitwear department one can buy sweaters,
cardigans, short-sleeved and long-sleeved pullovers, woolen jackets. In the
perfumery they sell face cream and powder, lipstick, lotions and shampoos.

In a food supermarket we can also buy many different
things at once: sausages, fish, sugar, macaroni, flour, cereals, and tea. At
the butcher's there is a wide choice of meat and poultry. At the bakery you buy
brown and white bread, rolls, biscuits. Another shop we frequently go to is the
greengrocery which is stocked by cabbage, potatoes, onions, cucumbers, carrots,
beetroots, green peas and what not. Everything is sold here ready-weighed and
packed. If you call round at a dairy you can buy milk, cream, cheese, butter
and many other products.

The methods of shopping may vary. 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.
