Wimpy Discrimates openly against White People

Myself and my elderly Mom went to Wimpy Randfontein and was seated, after some time a waiter came to tale our order and before he could he was taken by the arm and instructed to serve the black customers first, they were seated after us. This is unacceptable why is ************** against white people allowed? I have been a loyal customer to this brand for many years, they will never see me again and I will share on all my platforms including bitter einders if white people are openly allowed to be discriminated against they will then lose us as customers.
