Well, yes, and no.
Public system is a bit of a lottery. You must have had good timing.
I have been taken in to the Royal by ambulance - true, I was not actually at death's door but I was in great pain - and I was ramped on a gurney, in the ER hallway along with other unfortunates. The silly thing about it is that we were technically still under the care of our respective Ambulance staff because we were not yet admitted to the hospital. So we were surrounded by a bunch of First Responders (two to each patient). These were regularly checking on each of us, not the hospital staff.
So there was a queue of empty ambulances blocking the driveway, unable to respond to further emergencies.
