This is one of he funniest threads I've read in a long time!
I did meet a fellow TZ-er once, and it was in Rolex in St James. Well I say "meet" it was actually that we both posted that day that we'd been here and recognised that we would have been there at the same time.
I did see someone with a Rolex LV on the tube the other day and was tempted to ask him about it as you don't see many 'in the wild' but normal tube etiquette got the better of me.
