They aren’t licensed to practice medicine. I once had a pharmacist refuse to fill a script with the branded product, instead insisting upon a generic sub.
The physician had written “no substitutions” on the script at my direction. I could get the branded product free, while the Gx version would have cost something.
I had to take the script out of the pharmacist’s had and walk out of the store, and she ran out & tried to stop me. I asked her if she’d like me to report her for a HIPPA violation (which I would have), and that froze the arrogant witch in her tracks.
Screw these arrogant gatekeepers.
