If there’s ever a seat available, there exists a very clear hierarchy of who may sit. First, the attending gets to sit. Then if there’s another seat, the senior resident can sit. Then if there’s another seat, someone can put their purse there. Then if there’s another seat, a homeless drug addict who wandered into the building can sit there. But after the attending, the resident, the purse, and the homeless guy are all settled, any available seats are all mine.
