OK STILFONTEIN BULL*** SERVICE

I have just been to the store now and i am so disappointed by the service i received from Lerato Lehloo who was working at workstation 5, Terminal Id;694073. I got to her workstation she was busy chatting with another cashier who had knocked off. There was no greeting, she just continued chatting and tilled my goods. Then this friend cashier of hers packed the stuff in one plastic bag of which Lerato tilled 2 plastic bags. I then informed this other cashier about the 2 plastics bags and Lerato told me to give her the receipt then she said the friend can add another bag. I then said to her if one does that mistake you say sorry to your customer, she answered with an attitude saying that i got the plastic bag and i should just move away for other customers. I asked her if i said i didn't want the plastic what would she do because she is busy chatting with a friend while on duty and doesn't care about me as a paying customer. She told me that if i want my R.80 c she can give it to me there's no need to cry about that kind of amount. My complain is about customer service , not the money. You do a mistake and then you boost with attitude regarding that mistake and not even apologize. Is it what OK is teaching it's cashiers or what?
