Blatantly rude

I am absolutely disgusted in the service I have just received by your teller Robyn. When paying for my goods at the pick n pay dainfern square I was asked only after my goods had gone through if I have a smart shopper card , when I rep**** saying \yes\" Robyn blatantly rolled her eyes at me with no skaam right in front of my colleague and I, I then said to her that what she did is very rude to which she never apologised and rolled her eyes again while talking to the lady packing my goods away. I am disgusted and something needs to be done about this disgusting service in pick n pay"
