I know I'm late to the party... ... but quite honestly it doesn't help that Casualty (et al.) have so many "patients" who have had a funny tummy for a few days, or a bit of a headache, and aren't immediately told to eff off to their GP. Proud to say I've only ever had an ambulance when the dude on his own (FRU?) was giving me gas and radioing them to hurry up.
