Shell garage Benoni kleinfontein road

I pulled into the shell garage at benoni kleinfontein street, i i waited behind a car driven by a white lady. 1 of the staff attended to her, but her tank thing was on the other side, thats wen the patrol attended pulled the patrol pipe over her car to fill the car, i then saw this, i pulled into the next available patrol tank and i was told that i need to move my car coz the car tank is on the other side, i told them that they just helped the ada lady by pulling the patrol pipe over her car so they should do the same for me. I was told that i am not white n i should just move my car because they wont fill it untill i put my car in da correct position. These were black shell garage staff telling me that im not white so i wont get the same treatment. This is a disgrace and ******. Shell garage must teach their employees customer service.
