Segmentation of Retail Landuse: why do Germans only map shops?

de_retail_karlsruhe
Retail Landuse in Karlsruhe on OSM (scale 1:50k) :
both explicitly mapped and derived landuse polygons are shown, see below for methods.
The availability of lots of open data on various kinds of retail outlets has led to me doing a lot of maps of shops, restaurants, fast-food outlets and bars lately. I'm following in the steps of Paul the Archivist who mapped the Mansfield Road area close to pub meetings we had in 2011. I've got a nice workflow : I map my target area for an hour on Sunday morning, usually trying to get all retail establishments in a quite small area. I also try and collect as many house numbers as I can. I discovered my new mapping protocol, because my mother asked me to drive her to church a few weeks ago and I found it very productive. It also means I've been actively surveying in a neglected inner-city area.
