No stock og white wine for 2 weeks

Went to Paradise the last 2 weekends in a row on both Friday and Saturday nights and had no 500ml dry white wine. Their pathetic excuse was that their supplier did not have stock. It does not take a rocket scientist to thing of going just to the bottle store in the shopping centre and buying a few boxes. But "NO" it appears they would rather have a customer walk out and very upset about customer service. There are so many bars in the north of Pretoria to go to, but not Grasdak as they had exactly the same problem, except it was for 3 weekends in a row, not only 2. Disgusting poor and pathetic service. No customer concern
