No idea how to run a restaurant - Raw and burnt foods

I used to be a regular customer of Cappuccinos until this happened: On my first anniversary with my wife, we went to Cappuccinos in Illanga mall in Nelspruit so that we could have a nice dinner. We ordered crumbed mushrooms as a starter. It was COMPLETELY raw. I asked for a 500ml glass, the waiter did not know what I meant by 500ml. Had to go and show the waiter myself what I was talking about. Finally, I ordered their seafood pizza. Never in my life have I seen such a disgrace delivered to me from a kitchen. The calamari was as tough as leather. The prawns and mussels was rock hard. Felt like I was chewing a bunch of mixed nuts that tastes like fire roasted salty pilchards. I did not hesitate to call the manager. He offered that I pay only 50% on the pizza but full price on everything else (even though the mushrooms was completely raw). Given that it was my anniversary, and I was not in the mood for arguing, I just payed and left. However, the next two days I was sick to my stomach and I could not go to work. I had to give up my shift allowance for those two days. So all in all, I recommend that people just rather go to pannerottis instead as they are just around the corner, or if you want something else, there is a wide variety of restaurants to choose from at Illanga. I strongly recommend against going to cuppaccinos. Raw/Overcooked foods + untrained waiters + food poisoning leading to expensive antibiotics that I had to buy and days lost at work is not a way to retain loyal customers.
