Not CC but trod on David Beckham's foot once in the posh bit of Manchester Airport. I turned round to apologise and this tiny bloke said 'S'OK mate'. Quite shocked by how small he is. They were flying to Turkey for a match and lost.
Coming back biz from Changi to Heathrow with SIA (sorry girls, they are just the most beautiful cabin crew in the entire world) I was sat next to some Diva who was a 'name' can't even remember who she was but she whined for about an hour until yours truly had had enough and told her to STFU. Champagne arrived within seconds. Odd that...
Also nice to know that I recognise about 10% of the names mentioned in this thread, it's great getting old.
