Pathetic service and never have stock

I've never in my life come across such *********** staff members but the biggest problem is that I cannot believe such a big name like kfc grayston drive Sandton never have stock of product I have been there a number of times and every time without fail they don't have stock of something especially breakfast meals.the famous one is they don't have eggs or tortillas for one of there new very popular breakie crunch wrap meals I really cannot understand this and I think it is really poor, so no wraps and no eggs equals no breakie crunch wrap meal
