Very bad service

Asandiswa till number 11 checkers amajuba mall Newcastle store 4267. The cashier refused to take a R10.00 with tape that I had received from checkers Newcastle mall earlier she asked where I got the money which I feel is erelevant. With a very bad attitude she told me to me the clients that buy at the store don't take that money not sure what she was insinuating. Meaning I am not a client. I left her till went to money market and the cashier there about what I was told they looked very surprised. They said they didn't know such. She doesn't belong in client facing role she is very unfriendly and very rude and undermining as she was unproveked I didn't even engage her in a disagreement I just left
