Bad service - Menlyn Mall

Staff at menlyn mall need to be trained on customer service. Only two tills were operating even though there was staff everywhere. A staff member with a mobile card machine then came up to the line. I was at the front. She looked past me and asked the people behind me in zulu/sotho if they wanted to pay with a card. I understood her so i said me and followed with them. She turned around and said no i must stand in the line and took them with her. I asked why and she said it was because of my number of items. Another staff member with the same mobile machine then assisted me. I am apalled by this. Clearly my number of items were not the problem, she was. For me, her not speaking english and willing to only serve black people was ****** towards me(i am indian). I will not be supporting this store again. If it wasnt for the teller who served me saying sorry i would have taken this up with the manager and left my items. Mr price really needs to train their staff. Also with such a long line and so many staff around , more staff should be trained to handle the tills.
