I actually was taught in school to "never underestimate the stupidity of your clientele!" Ask any pharmacist and they could tell you enough stories of the bizarre and incredibly stupid to fill your day. I do not mean it in a cruel way, just honest.
While this seems to be overkill, CVS must have had many people call in discontinued medications in order for them to go to this extreme.
I should probably use that as my motto as it pertains to so many things, political, social, and personal.
