a bonus center is where they take all of the runners after they wreck too many trucks, slip a disk in their back, have to have 3 shoulder surgeries, etc, in the chase for the mysterious "bonus" everybody keeps hearing about. Anyway all of the said people get to live in this place, a sort of "center" for the rest of their lives after they get hurt and can't work anymore. They get to listen to recordings of DOK questions and get fed leftover chilidogs from the various hubs in the area that might have extra...this is a very special place.
