attitude towards black custormers

Today I went to multichoice in ermelo,when I got inside they we people in the queue. In front the was a white lady who was being service and behind her was a black lady and a black and myself. And we were all waiting for our turn to be helped. After the white lady was helped the consulted helped the african lady inn front of and when she was done 3white women entered the shop,and she turned her attention to them and they didn't even stand on the queue as she was with them signing receipt,entered a white guy with I think it was a DVD. She gave those ladies a receipt and she again turned her attention to the white guy asking him what's wrong with the device. And that's when I brought into her attention that we were in the queue and she answered me in afrikaans saying\ dat maak nie saak nie"I think it translate that's not important and honestly the service black people receive in that shop its really shocking and I just hope something will be done about it. I don't want to say their are ******"
