I see it all the time, I drive bus. One lady was caught by me, I opened my window and asked "what kinda phone is that? I'm in the market and..." She gave me some dirty looks and was chirping down the road, I saw lips moving. She never complained to my company though.
Another girl was doing it, i opened the window and asked "is that the iPhone?!?" She laughed at me and got away, I caught her again and she was still doing it an. Laughing when she saw me the second time.
