Internal injuries or a dislocated thumb?
Right, well get that diagnosis sorted before you put other people's lives at risk, please.
A CASA course in telepathy perhaps?
If the casualty was one of your children would you want a rescue helicopter to fly around in circles for a hour waiting for an ambulance to get there to diagnose life-threatening internal injuries or a dislocated thumb?
We don't put our lives at risk. We make informed, professional decisions and are paid to do the job.
