I have tolerated both rude patients and specialists, but few of the latter.
I have always given quick feedback to specialists when I think their behavior is inappropriate. In one case, it helped and he apologized. Most of the time I never find the results, because I will find another specialist, when I can.
With a large population of public aid, specialist options, even in medical mecca like Chicago can be daunting.
I do consider the source, but am quite willing to jetison patients who I feel are unnecessarily rude and may be a malpractice risk. Unhappy patients are more likely to sue, why give them a chance.
