I don't see many people wearing those except for a sales guy that comes in about once a month.
But just my observation, I could've sworn these are the same things we used to make fun of people when cell phones used to come out. Now almost everyone has one and carries them around all the time. I know not the same thing, but still the comments about "they think they're important".
How about beepers? LMAO Now those were pretty funny.
