You may think there's nothing wrong with the doings of that well-to-do woman.

Well, there's nothing definitely wrong as such. (As a practising physician like myself, you would find the behaviour annoying. We shall take that aside for the time being.)

But my question is: Was this kind of blinded testing an advisable way to seek a second opinion or look for an appropriate doctor to take care of her ?

As the old sayings: To the hammer, every problem is a nail. Yes, she would find the best expert (at least in terms of book knowledge) of that rare disease. It is equally likely, however, that this expert knows very little outside his field, or he may not be very good at practical procedures. (I'm not implying that's my professor colleague. Don't be paranoid.)

I am sure that pretty client would enjoy a good time should she eventually be under the care of a real expert who do not know the normal dosage of panadol.

PS. As to those annoying patients, we clinicians would not have discrimination - we always give them a fair treatment.

By the way, similar to our approach to medical students, there are two modes we treat our patients: fair or nice.
