Both Private and Warm
The best budget sleeping arrangement in the whole story. All you need to do is buy a newspaper, and you’re sorted. Of course, this one is stolen straight from the homeless people, who have been sleeping under the newspaper for many decades.
Come to think of it; some research has found that newspaper is such a good conductor of heat that it’s ideal for keeping warm, especially when guarding against the wind. For this guy, it’s all about having some privacy and guarding against staring people who want to pry about the guy sleeping at the airport.
