My history teacher told us once a story about when he received a French person home, it was on Rio de Janeiro I think
the person drank water directly from the tap, which... is a bad idea, and then needed to go to the SUS
that day, there was no lines; they entered, got a session, got the medicine, and everything was less than half an hour, and the person was profundly confused about who they should pay for the treatment
this person is now a preacher for public health system... based on this experience with the SUS
