Some years ago I was at a party and met the military liaison officer (unsure of exact function now) of *European country withheld*.
So, I'm talking to this guy over the drinks and dip and I decide to make some small talk.
I ask him 'so, what does a liaison officer do exactly?' he seemed a bit taken aback, but explained that he followed the general mood in the Netherlands and reported back about what's reported in the local media and stuff, plus some communication stuff with the Dutch military'.
Still in small talk-mode I started asking follow up questions and he got a bit fidgety and changed the subject.
Later a I told a friend about my encounter and he went 'Jesus, Eddie. you've asked a high-up spook what he does exactly for a living!'
What was funny, was that he seemed unprepared for some naive member of the public stupidly asking direct questions about his job.
I forget what his official title was, but it was bit like the famous "cultural attaché" that every Russian embassy has.
