Bad service

I always to Pedro cresta crossing and service the most excellent service and today I got the and received the most unpleasant service ever from Olwethu or it’s Lwethu she gave me attitude unnecessarily , her service was horrible she didn’t want to assist me and she was standing next to the till and kept on calling her colleague to help us . If the staff is angry to be at work they shouldn’t be angry at customer for no reason please.
