In the last year no less than THREE people have taking to referring to me using "Sir".
It's normally "Yes Sir"
or "Sir..." to get my attention when they need something.
These are not my buddies at work that I cut up and joke with... these are others who [GULP] look up to me.
I'm not aware of any other person at the office who is referred to using the word "Sir". At the company Christmas party one of the guys (who is actually senior in title) came to me and made a big fuss about how mush he admired me and how cool I was under pressure at work.
I'm not sure if I like being referred to as "Sir". Yeah, I like the respect, but "Sir"????
