This is true for pharmacies (which, by the way, can often check out your other groceries at the same time, up to a certain number of items). On the other hand, I think it would be unfortunate to conflate an eatery with the supermarket or treat it as just a department, merely because it shares an operator. Some supermarkets have whole food courts inside the main retail area. They may have generic or distinct names, but that’s a distinction to make in name or brand, not amenity. That said, I haven’t been going around tagging every supermarket meat counter as a shop=butcher, only where there’s something remarkable about it, and typically only in the markets that are large enough to be like department stores.
