Supermarkets are large self-service grocery stores that offer customers a variety of foods and household supplies. The merchandise is organized into an organized aisle format, where each aisle is numbered or labeled and has only similar goods placed together. The supermarket houses fresh foods, poultry as well as canned and boxed goods. Supermarkets are quite larger compared to traditional grocery stores, where people are available behind the counter to provide the consumer with goods and the consumer stands in front of the counter asking for the goods. However, supermarkets are smaller than hypermarkets or big-box markets, which are basically supermarkets combined with departmental stores.
