calling for an Ambulance might cost you based on the distance from where they pick you to the hospital, of course, you don't have to pay right away but it will be added to your bill once and if you are discharged from the hospital, why you think Americans buy generic pills from Walmart and do other things for flu, fever and other remedies rather than going to the hospital because they know it will break their budget and God forbids if someone gets a serious disease with a horrible Insurance than they are doom.
