Many years ago I helped a guy who came into a shop late at night. He staggered in with bad cuts to his face and he was clearly drunk. He didn't want an ambulance, he wanted the police. I checked him over and he was OK. So thinking he wanted to report an assault we called the police. When the law arrived they groaned and told us he was a regular who gets drunk, falls over and wants someone to call the police to take him home.
