Was it a private ambulance? Around here, there are some areas that private ambulance companies are forbidden. Just the hospital,fire, and police ambulances are allowed. Too many games were being played with the injured. Stealing patients, and the patients getting billed for a false call by the one they called -- and billed for a trip for the bastards that were listening in on the radio calls.
BTW -- Are you okay? Lawsuits in the air ??
