I'm not going to comment on the actions of this pharmacist but have to say that, overall, pharmacists in general are much more knowledgeable about medications than doctors.

I have had pharmacists intervene on my behalf when a doctor prescribed something that was contraindicated because of my allergies.

I just had to point this out because sometimes, yes, the pharmacists are more knowledgeable about medications than even the doctors at the mighty Mayo Clinic.
