I suspect in most companies, the public relations person is down at No. 20 in the pecking order. But here, he is fighting incredibly important battles. If a negative story starts running away with itself in the press and is not dealt with fast, it can badly damage the brand, and so we put enormous weight on our PR people.

I think sometimes when you come from a conservative background, you want to rebel a little bit. I dropped out of school at 15 and learned early in life that saying yes was a lot more fun than saying no.
