Rude and inconsiderate Cashier

Today, I met this rude old woman called Maria at the cigarrete counter by the Carnivall Mall branch. I gently asked her to process my express items since I was buying cigarrete. She was shouting and banging my items on the counter that she is not suppose to process items purchased from the main store. She also made me count my items one by one. Mind you she never greeted on my arrival and was wearing a heavy facial expression throughought. I think for you to progress and to have a customer like me returning, the solution is to FIRE her with immediate effect. Otherwise I and my close family and friends will never come to your shop again. POOR SERVICE, to say the least.
