The worst service I've ever seen given to a paying customer

I was standing in the queue whilst a lady was being served infront of me @ the food department. The lady politely asked the ladies at the deli if the item of food she was purchasing was prepared today or the day before. The deli ladies laughed and rudely ignored the customers questions. She asked for about 3times and got no response except laughter and funny faces.. The customer proceeded to report the matter to a white gentle man who I presume holds some sort of authority. They both came to the deli where the customer pointed to the ladies that gave her this appalling service. The deli ladies were still in festive mode laughing and pulling more sinister faces at the customer in the presence of this white figure of authority. I can't call him a manager as I believe a true manager would not stand by and watch what was happening to the poor customer. He did nothing to remedy the situation instead addressed the customer by saying to the customer there was no need to make a scene. How could the customer not make a scene when grown people a pulling faces at her and laughing loudly.?? I am a branch manager at Capitec Bank and understand that there are sometimes difficult clients to deal with but this case the customer did nothing to warrant such behaviour from the deli ladies and the white so called manager. I'm am truly disturbed by this experience and if was in charge at that Nick's food Spar @ Park Gates road I would releave all members that were involved in that display of poor customer service.
