A grocery shop is much more particular and generally not as big as a supermarket. Supermarkets are also awash with butchers, artisan cheeses that are hand-cut and shop meats, as well as fresh fish, but supermarkets are typically concentrated around a specific category of food or segment and have a more limited variety. The words grocery store and supermarket are often used in conjunction. The most frequently asked question about supermarkets is what time is the closest supermarket open.
