OSM needs to provide for objects that fall under more than one category, whether it is done by allowing multiple tags with the same key, using semicolon-delimited values, or some other means. One often-quoted expression is that "OSM needs to show the ground truth", and it is frequently the ground truth that objects fit into more than one category.

The thing is these services are also often available in supermarkets,
copyshops etc. and you don't want to put shop=photo on those.

And if a shop has both cameras and prints then you can use shop=photo if
the camera selection isn't that big like just some point&shoot cameras
or you can use shop=camera with some photo_prints=yes tag.

2 notes or shop=photo;camera is just not that great.
