Bad stinking service

I went to Mc Donald few minutes ago, ordered my favorite meal. The lady that served us was Ntombi. She had the most awful, stinky attitude i have ever seen. I asked her for fresh fries, she kept on ignoring me, i asked if she heard me? Why cant you acknowledge that you heard me? The response was that i heard you. There was no smile. Whenever Im there, if she services Whites or Indians she will be smiling but if its black people she just give them a stinking attitude. Please train the staff to show consistent service and not selective color Time : 17:11:26 Date: 01/01/2019
