The supermarkets and hypermarkets I’ve micromapped have been large enough that it makes sense to tag each department or counter as an ordinary POI. The concept of a full-service supermarket originally developed from bringing independent shops under one roof. The largest grocery chain in the U.S. still posts the strapline “Food & Drug” outside most of its locations, to distinguish these supermarkets from the adjacent but separate grocery stores and pharmacies it operated until the 1970s.

Consider that the bank branch, pharmacy counter, or optician inside a supermarket is typically tagged as an amenity or shop. It follows that the bakery counter would be shop=bakery or shop=pastry, the meat counter would be shop=butcher, and the cheese counter would be shop=cheese. If necessary, we could distinguish these departments from standalone businesses using operator or indoor=yes, or the department=store_section tag specified by this indoor tagging scheme mentioned earlier.
