Disgusting attitude from the cashier

The pricing on the shelves is not up to date and very misleading. My daughter and I had to go to the till for them to check so I can see which of the ice cream size I'd purchase. I explain to the cashier lady THULI LIFA worked next to the window on Thursday evening 31 August 2017 around 7pm.The Barbie doll make up set stated R29.99 however it's R69.99 on the machine. I explain to her that I need to check how much each item is, she starts speaking in Zulu or something how "these people" are giving her unnecessary work and that I should have checked prices properly as she calls out to someone to come void the transaction before that person knocks off. How is that my problem that the prices on the shelves is wrong and on the fridge it's not even there? She still had the nerve to say are you now sure you're taking these items.This country is full of respectful people that are desperately seeking employment. Right behind me there was a white lady that the cashier was being so nice to and calling her ma'am...I was appalled. My money is just as good. I don't care if I'm not called ma'am but I deserve the respect, do you not train your staff about proper customer service?My husband went in to get her name, I could see her through the glass flirting endlessly maybe she thought my husband wants to ask her out. Is your staff not used to assisting black women or the issue was just with me or the way I look???
