Tube pride: I'm always proud of my staff. The training we get on the Underground is brilliant, and it's refreshed each year. The staff take time out to talk to customers and help them. If there is an incident, they are very professional. My granddad, who was a chimney sweep, told me never to forget where I came from, so I like to spend as much time out of my office as possible, because that's where the real work is.
