Just a quick aside if I may. Whilst we were in the departure lounge at Houston many years ago there were lots of tannoy announcements asking individual members of the public to pick up the nearest white phone etc. In amongst all the announcements was one for 'Mr Pickle, Mr Dill Pickle please pick up the nearest phone etc'. We listened quite attentively after that to weed out the real ones from the fake ones. Maybe bored staff or someone trying to win bet of some sort!
