First time I saw a amanager in my company using one of those, I thought he had cracked and gone starkers. He was walking down the hall muttering out loud in a conversational way and there was no-one around for him to be talking to. I finally spotted his headset and deduced the answer but it had me going for a mo'. The last time I saw someone acting like that had been in the mean streets of LA, and the guy was a leathery, furry wino who was exhorting a hand-mirror in no uncertain terms.
