shop=Tienda ? What is the meaning of that shop value? What kind of services or products are sold here? Is anything from 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?

(if anyone wants I can provide list of weird shop values in some country/area - let me know if you are interested)
