Brazil, urban area, with a health plan (private healthcare)
I go to the doctor, grab a little paper with a number on it, wait for the number to be displayed on the monitor, go to the reception desk, give them my health plan card and my ID, they give those back to me, I sit back down and wait for the same number to be displayed on a different monitor. Once it's displayed, I go to the room number shown on the monitor and from there, I discuss what problem I have with an adequate specialist.
For an unplanned visit, the wait time is usually 5–30 minutes, depending on the hour and season (there are a lot of tourists during summer, meaning longer wait times and more people at the hospital).
I don't know about pricing (my parents pay for it), but it's probably not too expensive since we've never had financial problems due to health issues (as far as I'm aware).
I've never not went to the doctor for financial reasons, only for health concerns (worrying about getting sick with something else, specially if the waiting room is full or almost full). Sometimes prescribed medicine can be pretty expensive.
