turns out he wasn’t a cab driver but a graduate being interviewed for an IT job at the BBC; and thought this was all part of the interview!
He was also called Guy which added to the confusion … I think they should give him the job for being able to handle that; or kick out the numpty who got the two Guy’s confused and give the African chap that job instead!
Guy Kewney is a fairly regular contributor to the BBC’s science programmes (particularly on the World service). Although he’s a bit balder these days it is extremely unlikely he would have miraculously changed skin colour..
