Not a happy customer

Yesterday on the 26th on November at 18:00 i went to Pick n Pay at Reds Mall in Centurion, as i went to the kiosk to pay for wht2i came to buy, the lady by the name of Irene told me that "cant you see that we are chasing people to gi pay at the other tills" i didn't like that coz she didn't even great me as a customer, so i told her that that's not how to deal with customers, she then told me that it's non of her business, we started exchanging words, i then decided to leave her coz i was angry and i was gonna do something i was gonna regret later, when i left she started laughing at me as if i was a fool, the manager called me so she can apologize on her behal2, i didn't go coz she's not the one who had wronged me, after what happened i dont think I will go to that pick pay coz she realy embarrassed me. Something needs to be done about this, i don't think that lady went for training for her job.
