non staffed online only listings have always been forbidden.
there is absolutely no chance that the location is staffed at midnight and no indication from website that customers are welcome to visit.
there is also no indication that picking up orders onsite is even a possibility.
The denial i received was manual and received several hours after my edit. As the user reviewable edit q is jammed full of garage door repair and locksmiths in my city it is more then likely the denial came from a listings editor or other google employee or contractor.
Online only stores are not supposed to be on the map.
