I can totally see being upset with the people in administration and billing. But how can you be that upset with the doctors and nurses, when your whole complaint is that you wanted more of their attention?
A couple of years ago I fell for the high-complexity drug testing scam at the intake visit. It goes like this: you pee in a jar, and they send it to an out-of-network lab. A few weeks later the 4.5 kUSD bill arrives, which isn't covered by insurance. Everyone denies responsibility: the physician says you gave us the sample, the insurance says out-of-network, and the lab says services rendered. The charges eventually went away, after several afternoons on the phone.
Civil society offers no solution. It's no surprise that people give way to their anger. There isn't even a contradiction.
