Terrible cashier at PEP

I had a very bad expirience with a cashier at PEP in Suncardia in Acadia Pretoria. I will never step my foot there i wanted to a rug then it did not have price tag for her to see a price. She got very angry at me as if i work there putting prices.How rude can one be ? Do i work at PEP , so she wanted the price tag from me?What do i know about their price tags, is it not them who are responsible for price tags, is it not their job? On top of that she took the rug from me and through it harshly at her back as if i wronged her. Never will i go back there !!!
