Disgusting customer service

I went to Chicken licken in Dobsonville mall and was served by Thabelo she took my order, then some lady came with money and asked her if she wants change and she dropped everything we were doing and attended her.I told her I'm in a hurry can she pls process my payment and only for her to start telling me she is waiting for me to give her my card and that I shouldn't give her attitude and come cause "vurr vaai"... I told her I'm not in the mood to argue with her and she rep**** again saying even if I'm not in the mood I must not bring my attitude in the shop. The service was pathetic I am never ever buying at Chicken licken. You guys should make sure your staff is trained properly because what I saw and hear from that girls mouth was absolute vomit.
