Its always handy when you are in the ambulance service, and - whilst off duty in civvies - walk past a patient who is being a twat with your colleagues. You can call him all sorts, and he hasn't the slightest idea you are in the job. Very, very satisfying. By the way - the next series of "London Ambulance" (the series which was on TV a few months back) should not include major trauma or serious illness. It should feature the time wasters: at least the stupid bastards would be made to look stupid on telly!!
