Writing Heathrow's biography

Alain de Bottom is a brave, brave man: He's spending this week at London's Heathrow Airport to write a 25,000-word book about it which will be passed out free to passengers later this year. Smells like a publicity stunt, but he agreed to go somewhere most people never want to even when a vacation awaits, so hats off.

I want to know if he's actually sitting behind a desk like the one in the picture -- and if so, how many times a day he's getting interrupted by lost travelers. It's death by a thousand "What do you mean you don't work here?"s.
