Knock knock.
Hello?
'Ello, are you Mr CIM?
Erm, yes.
We're the CAA's crack intenet snooping dept and we'd like a word please.
The who?
Not the Who sir, we're the Civil Aviation Authority (brandishes large golden ID badge with skull and crossbones).
Aviation? I don't know anything about aviation gentlemen. I think you want the other CIM who lives down the street (points down the street and as they turn to look, legs it........).
Live and learn. At least now you know.
