not serving after 21H00

I have on 2 occations went to KFC in parkstation to by some meat and only to be turned away told there is no meat. The latest was on the 15th March at around 21:15 when I got turned then asked if I can speak to a manager. Asked her how is it posible that they open 24 hours yet at 21H00 there is no meat? The answer was that am wasting time cos she cannot prepare few pieces for me and the remainder will get expired the next day. Then asked me to leave the store. I went to the other KFC within the centre and got served with a smile. Worst part is that she refused with her name as she was not wearing a name tag then blatantly said I can report that anywhere she does not care. Such people will make KFC lose its loyal customers the people who r paying her salary. I wonder what is she teaching to her staff if herself does not know the importance of good customer sevice? KFC stop taking any1 frm the streets and making them managers please or else 5 years is a long time, ur business will go down the drain!
