When I lived in California I often heard people refer to it as “Killer Kaiser”. Michael Savage would sometimes devote a segment of his radio show to reports of Kaiser mess ups.
They explained the Kaiser business model. Ross-Loos operated on the same model but generated fewer complaints so, being young, healthy, naive and thrifty, I picked Ross-Loos.
Long story short, the first time that I had to use it, I drove three towns over to their nearest facility, waited my turn and got scolded for seeking treatment (a severe burn) for something I ought to be able to handle myself.
They changed the dressing and handed me an instruction sheet. At the next opportunity, I dropped them and changed to the indemnity plan. Yeah, it cost me a little more if I sought treatment, but I would be seeing somebody who welcomed the business rather than resented the intrusion.
