Worst customer service ever

I ordered only a pap and gravy. Waited for almost an hour. People who placed orders after me were getting them first. This is the worst service delivery that could ever be experienced. I asked for the manager he was too busy to see me. Finally he came and then the pap and gravy was delivered. I asked for my money back. Why should I buy from this restaurant when they do not care about the customers. If I could rate 0 stars I would. They waste the persons time , one hour for pap and gravy
