I live in America. But I'm originally from Ukraine. Therefore I have many friends and family from there and because of the current situation I've known many people that came and are still coming over from there and they keep asking the same question: you really have to pay for the ambulance?
Then I tell them ambulances are privet for profit companies. And you can see them loosing all faith in America.
Personal anecdote: my father died of cancer 4 years ago. When they were transferring him from the hospital to hospice the paramedics asked him if he was ready and Dad said yes, he was ready for the last car ride of his life... They sent us a 5000 dollar bill for a 15 minute drive.
We didn't pay it.
