I did a trial project with the goal of walking around a lab having readings appear for each piece of equipment as you approach it. Proximity detection was terrible... as it is, I don't think it's useful for anything but very gross distance estimations. Walking into a store will likely work but even then, the distance between stores would have to be pretty significant (or else other stores are presumed to not operate the same beacons).
