At the end of each busy day of customers bustling through the stores, Walmart takes on a completely separate purpose. It provides a place for the weary to lay their heads for the night: Its parking lots.

Money & Career Cheat Sheet reported that thousands of people choose to spend the night in Walmart parking lots each year. Some are passing through town and realize they can save a buck by not booking a hotel. Others have a less of a choice and are there because they have nowhere else to go. Through it all, the hosting of overnight guests is fine by Walmart, in most locations. One writer referred to it as a kind of urban campground.
