Heya, I often apply the "what would normal mapper do" test :)
It goes something like this: what would a normal mapper - perhaps me in a similar situation - do?
Sometimes I have the time to go through a shopping mall and map all shops with the opening hours etc.
Sometimes I can map the shops, but not the detail like opening hours, operators etc.
Sometimes I only have the time to map one shop from memory later.
Thus adding a single shop like that seems like a decent contribution to me.
Two items to check though:
a) Are the names legit? Seem to include category and other stuff that might not be a part of a valid name.
b) Is the location correct? Especially with shopping mall locations, company-submitted location data tends to be of low quality. They just dump shopping mall address in Google search or some other service and that's it.
When viewed in correlation with other shops and amenities later, this original location is a problem.
