Imagine you are a type 1 diabetic, are exhibiting flu symptoms (sudden onset of fever >101, chills, muscle aches, fatigue), you have two little kids in the house and a pregnant wife. Basically, the whole damn house is at high risk for flu complications.
You call your endocrinology practice (very large and affiliated with a major medical system in a big city) and speak to the doctor on call, to inquire about obtaining some Tamiflu.
The doctor's reply, "What? What's Tamiflu? I've never heard of it!"
Errr? How is this possible? This is supposed to be a doc who specializes in diseases that make people who are unfortunate enough to be afflicted automatically at high risk for pretty much anything!
Oh I'm so disgusted. He did convince her to call in the prescription, but the machinations of logic and persuasion that that required are too complicated and unbelievable to be described here.
