Some years ago (before the 9/11 flight deck restrictions) I found I had been seated on BA Berlin to London next to not just one but two, quite separate, UMs.
Just to humour things along, on climbout from Berlin I suggest to the boy, aged about 8, that we might enquire about a visit to the flight deck. That was a mistake ! Immediately "Can I. Wow. Oh, ask that lady [FA ahead in full drink service mode] there. Go on". I say we should do so only after the refreshments have been served. No joy "Ask her. She can almost hear you now. Ask. Oh yes ......."
Well eventually we did. What a relief to my eardrums those 10 minutes were !
