Rude cashier

The Cashier by the name of Maggy at Pick n Pay Springsgate is the rudest .I don't even know what her problem was .I was paying for something and I asked her for a R1000 cash back. She just kept quiet so when i was inserting my card that's when I noticed that she did not include the R1000 cashback .I politely asked her did you also include the R1000 and she was like "Just Insert your card " did she really have to be this rude I asked her why don't you answer yes or no ,that is when she said I must cancel the transaction and restart again as she noticed that she was busy talking to her friend instead of listening to me.She did not even see anything wrong in this as when i told her when you make a mistake you apologize .She just rolled her eyes. I am going to report this matter to HelloPeter can't be assisted by such people if a person doesn't want to work they must stay at home.Next time I come and she does the same I will take her a video and post it all over social media.
