Yes Delta I concur, when you are in a car accident, through no fault of your own, and the NHS ambulance is called, do make sure you stop the call and send them to some other "council" scrounger for treatment. I'm not proud I'll take an NHS ambulance anyday.
Then call your insurance company helpline, where hopefully they'll be ableto put you in touch with a specialist who hopefully can send a private ambulance to get you pending a review of you policy cover. Hopefully.
And if when those wonderous private medical folk arrive, why, the chances are they'll have been trained by the NHS, worked for the NHS or be temping whilst working for the NHS. And, to top off your disgust even more, you might even be sent to a private room in an NHS hospital.
And if yoy have any side effects or complications as a result of private care....they won't be covered by your healthcare and the NHS will have to foot thr bill.
But obviously being slim and healthy means nothing will happen to you, ever.
