I've arrived in London and am trying to figure out how to get from the airport to my hotel, when I encounter the guy who sat next to me on the flight. Sometime between leaving the plane and exiting Customs, he's been issued with a vacuum cleaner. We go to a pub outside the airport to get a beer. He tells me that he's come to London to start his new job on a cruise ship. His job is to vacuum the entire ship before it leaves, which will take 3 months.
