Rude cashier

I am extremely disapointed at the service i receieved from Pick n pay in Malvern, Queensburgh. I was purchasing a few items and as i rounded up my shopping i decided to pay at the cigarette counter. As i was making my way to the counter Jennifer Rameen was walking beside me hiding something (i dont know what she was hiding) but i tried moving away from her as she kept bumping me. Then when i approached the cigarette counter there was an indian male standing there with 2 little girls. So Jennifer Rameen was the cashier at the till so she serviced the customer infront of me. Then one of the lil girls kept touching the clear screen that seperates the customers from the cashier. Jennifer then spoke to the little girl and told her not to touch it and santized the lil girls hands. Fine. Then after the man that was infront of me concluded his payment he sanitized his hands (with the same santitizer Jennifer used on the little girl) and they were on their way. So i was up next made my purchase and when i sanitized my hands Jennifer then snapped and said and i quote " mam that sanitizer is not for customers, the customers sanitizer is by the door, i only sanitized the lil girl because shes a lil girl". So whats the difference between me and the customer that was in front of me? She did not say that to the man that was before me but she could say that to me why? Is it because im an African female? Why did she now have a problem with people using the sanitizer because i used it?. The reason why im soo infuriated by this incident is cause Pick n pay especially the Malvern queensburgh branch has always been our home away from home my family has been shopping there ever since i was a lil girl and to receive such poor service i am deeply hurt.
