Waited too long...

On Saturday (02/04/16) I took my sister's kids to Reno's Spur in Bellville. Firstly when we ordered our starter course, the kids ordered nachos and I ordered chicken livers, they enjoyed their food thoroughly, but I on the other hand had to sit and watch them eat for like twenty minutes, then a lady that looked like a supervisor came to ask if i'm waiting on my nachos and I said no the chicken livers. Then the African lady who served us came to say the food is on its way, well I still had to wait like a further ten minutes whereby the kids was almost finished with their food and the waiter gave an excuse that she gave the wrong order of mushrooms in the kitchen. The Bar-One shakes we ordered was melted when it reached our table. When I asked for the bill, a supervisor had to explain to me that my bill is not R248.25 as indicated on the slip, because they took off somebody else's voucher on my slip so I have to add a R100 to my slip, it is R348.25, I ordered three cokes and a glass of water, but I think I was charged for the water as another coke.
