Bad Customer Service

I was at Kfc mokopane Thabo Mbeki Street and pretorious. Just to step inside the service was very bad and the lady who was at till kept shouting us and we ddnt even have chance to say what we want to buy she was just rude saying there is no meat screaming like hell we did not even reach the till point. Bad customer service and its not the first time it happens please teach ur staff members about proper customer service and how to treat clients What she did was totally unacceptable!!!
