Cashier very rude and disrespectful

Female Cashier at Galitos in Witbank Sasol was very rude and unprofessional, unfortunately she removed the name tag, my husband and I arrived at the restaurant on 02 November 2019 around 21:35, as we were about to approach to her side without even greeting she just said ‘We are closed’ I then asked what if we are not to buy but to ask something she said ‘ Ask about what’? She was very rude and disrespectful towards us.
