Pathetic service Nolwazi cashier at KFC ruseel Street Durban

I visited KFC in Russel street Durban assisted by a pathetic cashier by the name of Nolwazi, who she failed to even greet me as a customer, when I asked her why she just look at me and not greeting me as a customer, her response rudely was like the customers normally greet her, I wonder why she chose to be in a customer service industry where as she is not customer orientated,
