?Supermarket{{/B}}
? ?Most supermarkets need a very large floor
area, sometimes at least ten times as big as that of an ordinary shop. There are
usually two doors, one as an entrance and the other as an exit. The rest of the
side facing the street is largely of plate glass, with goods or advertising
material displayed. The other three walls are normally decorated in light
colours, giving an impression of cleanliness (清洁)and brightness. Most
supermarkets are on one floor only. Goods being stored in rooms at the back or
upstairs.
? ?At right-angles to the window stretch long structures
about six feet high with a number of shelves on each side. Similar shelf units
or frozen food containers extend round the wails. Broad aisles(通道)between the
shelf units and ample (足够的)space between them and the window and also the far
wall allow room for the circulation of many people; Individual commodities (商品),
in tins, bags, boxes or other containers, are stacked (堆放) in groups on the
shelves, and each group is labelled with a price ticket. Metal baskets near the
entrance are taken by the shoppers who collect in them the goods they select
from the shelves.
? ?Between the shelf units and the window in one
half of the shops are a number of small counters about three feet high. Beside
each sits a cashier (现金黄色出纳员), who operates a machine ?for reckoning,
detailing the cost of each customer’s purchases. The customer places the basket
at one end of the counter so that it can be emptied by the cashier who records
the price of the commodities one by one, before putting each on a moving section
of the counter top. The goods are collected and packed into the customer’s bag
by another assistant at the end of the counter. The cashier finally hands a
printed slip recording all prices to the customer, who pays the total, collects
the bag and leaves. |
