Poor service Shell garage

Shell behind , flamingo shopping centre modderfontein, pulled in there at 3:08pm has 3 x petrol attendents on duty for +9 pumps asked for assistance, nobody came for 8 minutes when I approached 2 x petrol attendants I was told we understaffed and straight after that a red toyota FJ PULLS IN the 1 x petrol attendant saw me first but never came to me and I am to be honest I am driving a very inexpensive vehicle, compare to the vehicle that pulled in and I am Indian when approached attendant he says voetsek and throws his hand up, approached manager he say he will check camera and then see, after while standing with me sees them helping every white person not a black or Indian but as soon as white person pulls in immediately gets assistance how is this possible and guess what owners of garage are white , managers white
