I went to fill a prescription this evening for my sinus infection. After doing the paperwork, the pharmacy tech (who I don't know) grabbed the pharmacist (who I do know) to advise me. The pharmacist said "It's a new one??" and looked really surprised. I laughed and said yes, I do occasionally get new prescriptions.
I guess that's what happens when A) you fill half-dozen maintenance prescriptions a month for various members of the family, and B) you usually come in with great big dog in a service vest, so that EVERYONE remembers you.
