BAD, RUDE AND HORRIBLE SERVICE BY MARTHA "RUDE"

I have received an extremely Bitter and Rude service from SPAR BRONKHORSTSPRUIT now at 08:05 am. I will call the cashier who helped me Martha "Rude" she was contiously rude to me and I asjed her why is she so mean to me early morning and she couldn't give a damn she continued to say there is nothing mean about what she is sayong to me. My point is where is courtesy and customer cars at Spar Bronkhorstspruit!! The cashier attacked me verbally because I was speaking in Sepedi and she is Ndebele therefore she doesn't respond to Sepedi speaking people she can see my mouth moving but cant respond to me as she doesn't respond to what she doesn't know (my Sepedi language)! I was so offended! My question is: why do we continue doing this to one another fellow South Africans!! Martha was very rude, interacting with her was the worst thing that could happen to me in this day. I will not be making my way to Spar any time soon.
