Out of stock everything and long waiting time

As I arrived at the KFC (Hiilcrest Boulevard) I wanted to order something on the menu but the lady told me that they were out of Pops, Chips and Buns. So basically they just had chicken pieces. At 12 pm when the sun is at its highest they have no food available that is quite unacceptable. Quite a few people were waiting for food. I didn't order anything and I had to wait about 40 minutes to just get out of the drive thru lane. Fix your management problems. Your efficiency doesn't exist and you don't know what is going on in your own business. I am not going to that KFC ever again I would rather take my business somewhere else. McDonalds is much better than KFC when it comes to management and efficiency
