I live in the US. Every trip to the ER has had <5 min. waits. They're so fast, last time my kid had a fever I went there because the after hours pediatrician was a ten minute drive (10>5).

I thought they do, in fact, and the bill expires if not sent out in time.
Also, where I live there are five (?) Hospitals with ER within a ten minute drive... in suburbia. There just can't be that many people getting deathly ill sick.
