Great shot! He does look like a rather distinguished gentleman... my guess he isn't named something like John Smith.... got to be atleast three names there, and perhaps a Sir!
I'd say that almost passes for a 'posh bus stop'. You seem to have caught this lot completely unawares. I reckon MI5 could find some uses for you and your covert camera skills:)
I can sympathise with there "when is this bloody bus going to turn up" expressions!
