I think that the cited article may be confusing two technologies.

It is highly likely that no GPS, cell-tower, of Wi-Fi SSID location service at all was involve when when the 
mentioned researcher walked into a McDonalds an his phone prompted him to download a Mickey-D's App.

Rather, Google, and others, are encouraging companies to deploy Bluetooth based "beacons" in their stores.  The 
location those beacons is fixed and known.  Phones listen to the beacon signals.  Each beacon is named.  The phone 
contacts Google or Apple to resolve the beacon's name into an action, such as prompting the user to download a store 
app.

This of course, means that your location is known, and is provided to Google (or Apple or ..), but the location 
information comes from proximity to the beacon, not from any GPS or cell-tower based location service.

(This is not to say that these beacons could form yet another source of location information for the location 
services in the phone.)

Delete Google Maps? Go ahead, says Google, we'll still track you
Google Play services need constant location info

Needless to say, this is not making some users very happy. Security researcher Mustafa Al-Bassam reported on Twitter 
that he "almost had a heart attack" when he walked into a McDonald's and was prompted on his phone to download the 
fast food restaurant's app.

Al-Bassam dug into his phone's apps to figure out how that had happened, and was amazed to find that his suspected 
culprit – Google Maps – was not responsible. It was Google Play that had monitored his location thousands of times.
