If he's "pedantically" noting down details, I'm sure it's not out of personal interest. The guy's got a job to do to pay his bills too and I can see his employer wanting to see evidence of who's about, although the job can be done without the attitude.
Eg.
"Morning, just need to grab your ASIC details for the records if I could please, thanks Boss." (with a smile)
Vs
"Where''s your ASIC pass?" (with a brick wall attitude)
I know which one would get friendlier compliance.
Catch more flies with honey.
Shame some security guards (power trippers) don't realise this.
I know, I worked in security for ten years including a year at an airport.
Then again, if it wasn't for 9/11, we wouldn't have all these dramas.
