CVS review: Sexism and anti-disabled bigotry

I was at the CVS at 4627 N. Main in Columbia SC as I'm stuck with it due to my insurance. The pharmacist ORDERED me to "sit down and stay" as if I was a dog! I was trying to get a prescription refilled and told him The head pharmacist insisted that Amlodipine was a water pill and I didn't need it! It's a calcium channel blocker I've been on for months and controls my hypertension! (He's an Indian-descent man, for reference) I don't know his name, he's told me several names so I have no idea. He's been there for months. Why doesn't CVS at least do a simple background check?!
