Not to mention the cost of the ride there! My mom had to go to the ER a few years ago. We called 911 and an ambulance came to our house and transported her to the local hospital. After she got out, she got a bill for the ride for $2800 (which is actually pretty cheap for an ambulance ride). Then, a few weeks later, she got another ambulance bill for $2800 from a different ambulance company. It turned out this second company was the one affiliated with the hospital, and this made them feel entitled to bill people for a ride even if a different company's ambulance showed up and actually provided the service.
My mom was all set to pay this second bill because she's from a generation where they just pay any bill that shows up no matter what. I was like no fucking way are you paying this, and I called up this ambulance company and allowed myself to get really angry on the phone. They threatened to send it to collections but they never did, maybe because I yelled "fucking do it!" to them over the phone. Just the shittiest pieces of corporate shit I've ever encountered, sending out completely illegitimate bills to old people because they know some fraction of people will just pay it.
