Rude at the Rite-Aid in McLean!

So, I went back and showed them the policy. The manager maintained that she'd done it right and told me that I was wrong. Then, I just asked for a return and she said fine. She gives me my money back, and then BEFORE I EVEN LEAVE THE COUNTER, she starts talking to the cashier about me! About how I don't know what I'm talking about (nevermind that I showed her Rite-Aid's own coupon policy that proves she is wrong). I will not be shopping at THAT Rite Aid again.

I just got off the phone with customer service rep Steven (who was very nice) and he assures me that this is not a habit in Rite-Aid stores.
