Rcaffe ripoff you pay before getting bill

I went to R Caffe on Long Street for a coffee and a meal. There are no coffee prices on the menu, nor underneath the types of coffee advertised on the wall. I asked for a price from the waiter, for a latte and I was told R24, after I insisted he asked the manager, because he had said \around R30\". I accepted this and ordered one and my meal. The latte came in a cup so badly chipped on the handle it dug into my hand. I sent it back and waited and waited. It came. So did the meal. Ok. I requested the bill. It didn't arrive. I went to the woman behind the till and requested my bill. She wouldn't give me one. She said she had many orders and was busy. She quoted a rather round R80 and took my card. I paid. Only then did she give me the bill. I was charged R28 for the latte, and I was charged a R7,00 \"Service charge\". If everybody gets ripped off in this way, she will be coining it. I left, and am now taking further action. "
