I worked at the tire center in wal-mart when I was in college. To accomodate my school schedule I started at 2 in the afternoon and worked until the tire center closed. Then I was supposed to work with the people inside doing whatever they did for the last few hours. They never actually told me who to report to or what I was supposed to be doing for the last 3 hours so I would just go sleep in my car then go back in and clock out at the end of my shift. I did this for like 9 months and no one ever questioned me.
