Bully of a cashier

I was just at your dischem Brooklyn branch and I am ****ed off to say the list at the level of service I got from your cashier N. Rashelo ( 123175). I was waiting on the queue waiting for the promoter to tell me which cashier to go to, while waiting I received a call and obviously couldn't hear where I should go but only to see the till to which I should be assisted. Turns out I was next on her till and she was impatiently waving at me I had to cut my call because she was rolling her eyes huffing and puffing like I had committed a crime. I was shaken by her treatment and apologised because I realised I was wrong.. she banged my card on the counter telling me it's invalid, insisted by pointing with her head that I move my things closer.. usually I call people like her to order but I was shocked by her level of non professionalism so early in the morning and to think this is where I making a lasting impact on a client. A cashier next to her had a difficult client and she said she wished that client had come to her " she " obviously sorts out customers in your store. A part of me wanted to reprimand her but the way I am shaking I felt I am going to make a scene and get no resolution.. I am a regular client at your stores and I am highly disappointed to say the least at the level of treatment I received from your cashier.
