Chad's Bunk

Most days, we'll arrive at the normal time and Chad will be there to greet us with "I've been here since 2am!" We're not sure what to do with this information, other than suggest a good therapist or over-the-counter sleep aid. Recently, Chad awoke at his house--in his bed--and decided to come in to work in the middle of the night. On the way, he stopped at a 24-hour Wal Mart and purchased this cot on which to sleep at that shop. Our question was, if he's tired enough to sleep at the shop, why not stay home? Still haven't gotten a good answer from him on that yet.
