horrible/unprofessional, BAD manners and un accetable behaviour

I always buy my breakfast at KFC almost daily, but I have never received the treatment I received this morning at KFC Kaafontein (Allandale). I was on the que and 2 ladies was busy serving Coffie to one of the client which come before me, then i asked them how can they both serve Coffie while we are standing on the que. then the other lady by the name of Lindiwe Masuku come to the counter and i walk there to get helped, then he shouted saying to me how come she was seeing us then ask me what i want which i tell her when she done with my order she shout to the one at back who is preparing food, said with sotho lanuage (o feng brekkie pele ga a re bolaya) meaning give her brekkie before she kills us, then i asked her if that is how she was thought to treat customers but keep on shouting to me till i tell her i am going to report her. she needs to be taken for a customer care/treatment course she real needs that the way she spoke to me it was she is talking to her friend or something forgetting that she is not doing me a Favour to serve me. One thing i notice is workers of institute like this at the township don't take customer seriously. she (Lindiwe Masuku) needs to be called in order or else will call her in order.
