PnP Cornubia staff is RUDE!!!!

Yesterday i went to PnP in Cornubia Mall , so when I was at the till one of the staff members came to ring her groceries , to my surprise the strawberries and other fruits and vege's were marked down , my interest was in the strawberries as they were R1 , the woman at the till gave me an attitude , the the girls i was with went to the vege section to beg the people there to give us the vege's and fruits at the price it was marked down with i was left at the till , that woman said " yhoo ngaze ngacikeka manje " meaning that she was getting irritated by us , am not sure of the level of customer service that is taught to your staff but that was totally unacceptable, I couldn't discipline her cos she is elderly but i felt so undermined when i will be paying my own money !!!!!
