Kauai The Village Square Durbanville-Rude staff, poor service

The cashier at Kauai The Village Square Durbanville, very rude and sarcastic. I was told by her that their card machine and redeeming of Vitality rewards on operate from 09:30 hrs onwards. When I came back after 09:30 she was sarcastic, got our order wrong and not apologetic. I called the owner, he sounded as if he the knowledge of customer service too. A very poorly run outlet.
