KFC Nina Park operating times.

What time does KFC closes? I went to KFC Nina park today and the door was closed the employees were cleaning. They told me they are closing at 21.00 because it’s a holiday. The time was 21:23, but I decided to go to KFC Pretoria north. It was business as usual, the employees were still serving us with a smile. Are KFC franchisees operating differently or KFC hired lazy team, who decided to as they want??
