I get where you're coming from but pharmacists have the right to refuse to fill a prescription and in fact can be held liable for not doing so. Pharmacists are trained medical professionals and are expected to use their judgement
Judgment based on what? The five-second interaction we have while they're doing twenty other things thirty feet away?
It's one thing to use their judgement to refuse somebody who is going to get a bad drug interaction, and another for a pharmacist to say "I've given out too many of X prescriptions, I'm going to start cutting off people from their prescription based on my judgement of them," and this latter one is what was under discussion and the one that I'm rejecting.
