Cashier's inappropriate attention for male customer and insults to my under-aged daughter

@shoprite in Witpoortjie on Dirkie Uys street today...cashier Vuyelwa was so rude to me. A few customers (and I) waiting in her queue, I was next to go but had to wait while she(normally most unpleasant and least helpful) stepped away from her cash point to personally load up a certain male customer's trolley while we had to queue and watch her flirt with this older white customer. She normally refuses to pack any non-white's shopping but took it upon herself to not only pack his purchases (I have no problem with that), but also start loading everything in his trolley for him. When I asked if she can please step away from this client and come back to her till she deemed it fit to verbally attack me and say mean and nasty things about my daughter (who was not with me today and aged only 15). I normally shop there with my child, but I was alone today. I asked Vuyelwa to refrain from bad-mouthing my child in front of other customers in the queue who do not even know my little girl. The manager had to step in since she decided not to cash out my purchases. She refused me service and embarassed her manager by refusing to take his instruction to finish off my purchase. She crossed her arms and refused her supervisor's request (who was called by the manager because Vuyelwa would not respond to his calm and reasonable requests) and her manager. The supervisor had to finish the sale. I am very disappointed in Shoprite staff defaming my child who did no harm to any and had nothing to do with Vuyelwa's inappropriate attention to the customer whom she was so openly inappropriately making advances on. Her lack of self respect and seemingly desperate need for attention from certain men should not hinder her job. That behaviour is perfectly fine in her free time, not when we female customers simply want to purchase our items and leave without hassle.
