"Did I miss the part where someone held a gun to their heads and forced them into being a pharmacist, whose job description entails dispensing the medications ordered by physicians for their patients, and only the medications ordered by physicians for their patients, and any medication ordered by physicians for their patients?"

Where, may I ask, did you read a job description for "pharmacist" that equated the profession with a pill-dispensing vending machine? Where are you getting this "only" and "any" language?
