Worst Service

I went out for dinner with my wife, after eating we requested a bill and to a shock the bill came to R2400. I asked the waiter why so much and when we checked the bill I saw the are things added to my bill that I did not have on my order. I asked for the manager, he came to our table and we asked the waiter for the bill which at this point he had changed and threw away and still denied what happened. He gave another receipt however that receipt also had drinks that I did not order. I showed the manager and after fighting and complaining the bill came down R818. I don't understand why a waiter would charge more and charge things that are not part of your order. The service there was disgusting and I will never ever recommend anyone to go there. Their food was also dry and did not enjoy it at all.
