Not as extreme, but I burned my hands on bacon grease a few years back and needed a trip to the ER and some bandages on both hands. When they were signing me out, I asked what care I was supposed to do for the bandages and they said to come back tomorrow and someone could show me.

A few weeks after, it was quite a surprise to receive a not one, but two pricey ER bills!

While the hospital ended up waiving the second visit, I imagine many people either pay it or go into debt especially since it required a couple of hours during business hours to sort out.
