I have actually just had a brainwave and hit upon the exact, perfect solution to this - one that won't frighten the many vulnerable elderly out of calling when they need an ambulance, but which will take care of the foot-wart crew in no time at all. Ladies and gentlemen, it is this: Give the patient the full conventional medical treatment for the problem they complain of. In its most serious form. Think about it - someone calls in with a cough ("chest pain") wanting antibiotics they can't be bothered to get from their GP - ambulance crew gives them a full course of defibrillation, and perhaps an open-chest heart massage. Person calls in with a sniffle ("difficulty breathing") and gets stuck into an iron lung for 3 months. Person calls in with a wart of their foot - super, field amputation, quarantine them for having that necrotising flesh-eating bug thing, and then give them the treatment for leprosy just to round stuff off. Maternataxis could get off lightly with an emergency caesarian, while all drug abusers could be shot into space in special life-support capsules to detox for a few weeks, since "getting high" is the aim of the game after all. Stupid, I know, but the idea makes me happy! :o)
