I wiuld call in as a student complaining about a running nose and would get an appointment withing a day or two.
In the past few years it fell off a cliff.
Recently I called in about a serious infection and got told there are no appointment left this month. At all. It was the 2nd of March.
Thr only way to get treatlent is to go to the accidents and emergency department of a hospital and to sit for 6 hours in a queue.
