Maybe as doctors they took the Hippocratic Oath to “first do no harm.”
Without an understanding of a patient’s medical condition, any decision they think they are entitled to make in variance of the physician’s orders could be a harm. They are acting as presumptuous jackasses, and should be fired- if not by the pharmacy, then by the patient.
They are no more “medical doctors” than a PhD in biology. They aren’t licensed to practice medicine.
