Yes. A couple of times.

Have I ever paid for antiquated inhumane treatment that included "no painkillers" for a painful condition the wife had. Yes, more than once. In a proper hospital the same things would have been done completely different and free of pain. 

Have I been offered TCM treatment with the sidecomment from doc "It will not help you heal faster but some people like to have some medicine in any case" He forgot to do airquotes when he used the word "medicine" but hey. 

Have I seen "well meaning" people suggest trying wacky things to cure a dying family member.... "Here, if you put this squirrel between his feet, he will be up and running in a week" .... "Oh, no no no, you cannot just use any squirrel, it has to be this special squirrel" 

Have I seen a woman try to kill herself by jumping from a hospital window.. Actually no, I missed that by a couple of minutes. I did see how the relatives treated the hospital staff while they were trying to save the woman. She made it through her fall, only 3rd floor. 

Have I ever been to a hospital and not been cheated, or seen someone be cheated. Nope. 

No never have. I thought the prices for some things were rather high, but still that's not called being cheated just overpriced. I knew what the price was and that was the only place that I could go to get the checkup done.
