Apartheid in Master Harold and the Boys

Apartheid is a clear way of segregating whites and colored people. In Master Harold and the Boys we see an example of Apartheid in the last part when Sam reminds Hally of the kite flying they did when he was younger. Sam made the kite for Hally and took him up on a bench on a hill to watch it fly he was not able to sit with Hally because the bench was "Whites only" meaning people of color where not allowed to sit in them. I also believe that Harold demanding Sam call him Master Harold is an example of apartheid because he was attempting to degrade him because he was black.
