A possible bug is showing those business owners who can manage their Google business listings within the Google+ Local interface the locations their business is serving customers in.
A Google Business Help thread has a business owner who wrote:
In a Google+ Local Page, when editing business details, I noticed the address section is showing "Serving Customer in+city_names". When selecting the address field for editing, the address does appear.
Here is a screen shot:

Google's Jade Wang said this is a known issue and wrote:
We can confirm that some users using the Google+ page interface to manage social local Google+ pages may be seeing information about service areas. This is the result of a technical issue and does not affect the way the listing appears live on Google Maps. Thanks for reporting!

Random, but always fun to see when internet marketing examples are close to home! I've passed by Emkey many times.
