I was given a bad attitude at Ocean Basket Wonderboom Junction

Me and my wife went to Ocean Basket WonderBoom junction on Saturday the 2nd of December 2017 around 9PM, I am a regular customer there, and when I got there people were seated waiting for their orders, I was told by the manager that they are closed. When I asked what time do they close, they said 10PM, and I told them it is only 9PM and I was refused to enter the restaurant. I ended up going to spur immediately after the scene. The question I am asking my self is, was this a ****** issue or what, because most whites were seated and probably waiting for their orders now why was I kicked out at 9PM they could not even try to offer me a takeout.
