It always surprises me as well that people wait hours and hours for an ambulance. I would get in my car, ask a neighbour, or even call a taxi.
If it that urgent I certainly wouldn’t be waiting around for an ambulance.
If it was really serious once you got to the hospital then you would be triaged in.
Just waiting for the doom and gloomers who say they don’t have a car, and cannot ask their neighbours etc etc.
