Last night my wife and I had dinner at a restaurant not far from our home. We like this place very much, but we have eaten there many times. Last night, otherwise, the service was not very good. We had to wait a long time after a waiter came to our table. He was very nice, but he didn't do the very good job. I ordered chicken with mushroom, but he bring me chicken with cream sauce. My wife got her main course OK, but she put the wrong kind of salad dressing on her salad. We didn't say something to the waiter. We just ate what he brought us. I know that 15% is the unusual amount for a tip. I wanted to leave 10% show that we were not happy. Did I do the right thing?
