Universal-Care citizen here. Let me explain how it works. It's definitively not "first in, first served": when you reach the place, you get "pre-examined" by a doctor, who estimates the urgency of your case. Fast, like, in minutes. He assigns you an "urgency level". You then have to wait more or less depending on that. I don't know the exact algorithm they use, but I would assume it's some kind of weighted queue. If you go to ER with a headache, you will have to wait for a long time.
