Frowning at customers

Went to Mr Price at Sammy Marks and while in line I hear them ask for cash only, so I assumed they were talking about people who were not using the Mr Price card to buy. I showed her my debit bank card to ask if that's OK since the didn't specify they they don't want any cards but hard cash, to which the cashier rep**** with a frown or look of disgust that she said cash only. From there she seemed angry or something along those lines.

I didn't expect to get such a heavy attitude for asking if a debit card was OK. The service and attitude was uncalled for and with cashiers with such actions towards customers it make you not want to shop there, even if they have great clothes.
