from this article: Private Eyes Are Watching You: Twitter Oversharing and Its Bizarre Real-World Consequences
Something peculiar happened yesterday.
I was sitting in a coffee shop near work as I often do between sessions when one of the baristas sheepishly approached me. I go in there all the time, so most of them know me by face, if not by name. She said, “Are you Jeff?” I answered in the affirmative and she goes, “There’s someone on the phone for you.”
My first thought was that it must be work calling to tell me that there’s been a schedule change. AT&T has spectacularly terrible coverage and this cafe could be a dead zone. One look at my phone confirmed that I was five-bars strong and I had no missed calls. She looked as quizzical as I felt. I took the cordless phone from her and the conversation went something like this:
Stranger: Is this Jeff?
The voice sounded hesitant and I definitely did not recognize it. I was slightly discombobulated that someone was calling me at this location, but curious and attentive.
Me: Yeah, who is this?
Stranger: This is your neighbor. Did you just check in on Foursquare?Click here to read the rest of the article
