I've noticed that more and more people are using the bluetooth headsets out in public. They have a practical use in the car, but then again, why not put your phone on speakerphone ?
Without knowing that they have a headset, it appears that they are talking to themselves which looks odd.
Yesterday I saw some guy at a hotdog stand with a headset in.
I could only surmise that he was of great importance that his presence would be needed at moments time, despite working at a hotdog stand.
