treating valuable customers with disrespect

I write this complaint out of great disgust in the manner we were treated at kathu 2 kfc, we went to buy a 8 piece family meal, all we asked for is for is breastfeeding and drum sticks because we don't eat other pieces but when we enquired at the drive through your so called supervisor was so rude, I even went to an extend to ask her why is she so rude, I think this lady has a problem, we went home and the pieces where not what we wanted I ended up giving the dog to eat, I suggest that a quality manager give me a call, we buy kfc every week, and this lady ****ed the he'll out of me, I don't think I will ever go back hear again, she must learn that we pay her salary, not her attitude towards loyal customers,
