Well they eat the food they sneak in when they're supposed to be NPO before surgery and little do they know it increases their risk of aspirating while they're under general anesthesia in the OR. As a result, they develop aspiration pneumonia. Laws state that development of aspiration pneumonia is 100% the hospitals fault so insurance doesn't pay for the treatment of it (generally at least $40,000). So the hospital absorbs the treatment cost and then has to pass that cost onto other patients. "BUT MY FAT DOESN'T AFFECT ANYONE ELSE."
