dj6 If I was greeted like that, I think I would need the loo very quickly! On a more cheerful note when I was recognised on disembarcation ... LHR T2 in the mid-1990s. I was returning from a biz trip in Oslo and, as I walked up the jetway, my cousin was waiting at the 'elbow' when you turn to go up into the terminal. She was working for (what is now) Border Force and was on the lookout for certain people. I learnt the plan was to nab them before they got to Passport control and find out what they were up to.
We greeted each other and walked off up the jetway together. A ground staff member of SAS ran after us anxious to find out if they had carried an infidel into LHR. They had only seen us walking away and not that we had hugged and kiised!
