Worst service

When you buy through drive through check your order before you drive off .theres always something missing,last time i ordered KFC at Newcastle corner and it is the 4th time they do this ,They didn't put my drink,the second time they didn't put my pops and I went back to tell them. Third time I ordered 6 piece they put 5 I checked before I drove off and showed them,And they have a tendency of giving people soda water instead of sprite
