In 1980 I was a conductor on the London buses. One day I was working on the number 11 route. We were travelling southwards along Whitehall, where there is a request stop. The bus was full but some passengers wished to alight there so we stopped. I could only allow as many people to board as had got off (the number of passengers that a bus could carry was strictly regulated by law in those days). I counted the people getting on until the bus was full then stretched my arm across to block the flow of boarding passengers and told them that we were full. The next person waiting to board was wearing a dog collar (i.e. what Church of England priests wear around their neck) which was a very ornate purple and white rather than the ordinary black and white. This fellow got very agressive, tried to force his way past my outstreched arm and let lose a torrent of abuse which included the 'F' word. I was somewhat taken aback to experience such behaviour from a clergyman, but gave it no further thought.
The next day I was glancing at a newspaper when I got a shock. I saw this same clergyman's picture in the newspaper. From the newspaper I learned that this man was the Archbishop of Canterbury!
