Sounds like every day where I work. I am in A&E, and we see the same lot, day in and day out. When I worked at Charing Cross A&E, there was this bloke who would phone for an ambulance from the top of the hill, come in to A&E complaining of chest pain, and then leave before he was seen, only to walk to the top of the hill and phone for an ambulance again. He did this for over 2 weeks, about 3 or 4 calls a day, until we showed him the discomfort that certain tests caused - he stopped after a few arterial blood gas samples...
