A similar story told to me by a vastly cleverer mate than me
He is a lecturer in a well known school of pharmacy. If he gets a prescription, you can be sure he knows more about the pharmacology, side effects, and dose regime and interactions than the average GP.
Cue him having to collect a scrip from his local chemist. The assistant started to give the talk very slowly spiel, to which the pharmacist behind the counter piped up, thats Dr xxxxx. I'm his ex student, and i can guarantee he knows all about that. Just hand the damn stuff over.

To be fair I don't have a problem with them doing the mandatory double-check ask about "are you allegic to penicillin" and an address check when they hand over a course of amoxycillin. The usual, yeah taken them before is sufficient, but giving the third degree to someone with a standard scrip should get their arses kicked
