Bad Attitude

I visited Evaton Super Spar yesterday around 6:00 evening to buy my grocery, after buying my grocery I then decided to go to the Kiosk to buy the Powerball Ticket, the cashier (Martha) told me that she was not willing to assist because I wanted to pay with the R100 note, she also boasted that I can even report her to her supervisor she doesn't care. I then reported her to supervisor she was still showing some signs of arrogance towards me. I feel that I receive a bad service from Evaton Super Spar and am disappointed
