Rude cashier

I just got off the gym and I needed to stop at Walgreens on my way home to get some stuff. When I’m paying the cashier told me I had $5 in rewards available and that I could use it for perfume...

BITCH I SMELL LIKE GYM BECAUSE I JUST WORKED OUT! YOU DON’T KNOW IF I HAVE A SKIN CONDITION THAT MAKES ME SMELL!

It was extremely rude in my opinion. Just needed to rant.

EDIT: the reward is not directly for perfume. I never get suggestions as to what I can buy with those rewards. Her body language was very obvious.
