Bad service

The cashier Anna Khwasa,so rude I ordered a pizza the one on special for r129 so I wanted to first confirm which flavors goes with the special without a smile she push a menu in front of me.. I let it slight then she gives me a number I then tell her that I'm gonna need a receipt for it she said she will give it to me. Then the guy at the back called my number when i went to collect they way she presented my pizza to was even more rude she opened it and said nothing closed it and just stood there. When she saw that i was not moving she then asked me if I am still waiting for something I said yes ...she looked at me giggled and said what I'm waiting i reminded her that I need a receipt..she just said 'oh I forgot ' ...looked for the receipt and gave it to me without even apologizing...damn I really didn't like her service and I am not happy with this. I work with customers and I respect then a lot and sometimes force myself to smile even if I'm not having a good day.
