PATHETIC SERVICE & DISRESPECT

I have been really disturbed by a lady by name of Nontshukumo's customer service and conduct when dealing with customers, the way she speaks to people is really disappointing, I couldn't take it anymore yesterday when she was serving an old man estimated between 65 and 70yrs old after he requested Nontshukumo to give him two pieces that can be accommodated in his R30, Nontshukumo then insisted the old man to say what's on the menu/specify what exactly does he want instead of just saying two pieces that can be accommodated by the R30, she then asked an old man to move aside so she can assist the next person(while checking KFC menu)...that was very harsh, rude, disrespectful considering that poor old man could be unable to read(for whatever reasons), I was really disturbed by this kind of behaviour and I am not sure that this is what describes Customer Service...that old man could have been assisted with respect even if it means educating him about KFC streetwise two or any available special. I was even more disappointed hearing one of the customers in the que saying \this lady has a stinking attitude, he then started counting incidents where this lady has been rude and harsh to him"
