Task: Question Answering
Input (English): I went to a sushi restaurant by myself last Friday. I like to sit at the sushi bar because it is easier to get good service, but the restaurant was very busy, so I had to sit at a table instead of at the sushi bar. A waitress came to take my order. I ordered a spicy tuna roll and the waitress said my order would be ready in about ten minutes. When the waitress brought my order, she didn't bring be a spicy tuna roll, but instead she brought me a California roll. I told the waitress she brought me the wrong order, so I had her take it back.  After about ten more minutes, the waitress came back and apologized for bringing me the wrong order, and she gave me the spicy tuna roll I ordered. The waitress felt so bad she offered to pay for my sushi.
Output (English): What was wrong with the order?
