name=Sanitär-Heinze

shop=sanitary ? What is the meaning of that shop value? What kind of services or products are sold here? Is anything from https://wiki.openstreetmap.org/wiki/Key:shop fitting? Maybe new value needs to be invented? Maybe this data is wrong and there is no shop here? Maybe it is not a shop but something else?

name=Elektro Haag
https://www.openstreetmap.org/node/269663652

shop=electrics ? What is being sold here? White goods/domestic appliances? Electrical supply contracts? Electronic elements?
