CVS review: prescriptions

I have only been to this pharmacy a couple times. My wife's company has their script service hooked up with them. I had JUST had oral surgery and had a script of narcotic & antibiotic to fill. Was told by the pharmacist it was LAW that I had to fill both (I didn't want to fill the antibiotic). When I pressed that less than a month before I had another procedure and only filled the narcotic she said "Well, it's an agreement with the dentist!" I said "THE dentist? Who the hell is THE dentist? It sure isn't MINE!" She just walked off and refused to fill my pain meds. But since my jaw was swollen like a walnut I just acquiest & paid for both. This kind of crap to get you to fill more meds than you want is not only dishonest but I'm betting illegal! How the hell can I trust a pharmacist who would lie to get more business? I will drive to the next country before I fill another script here. And it's within walking distance of my home!
