I've walked out of an Olive Garden because I sat down and nobody came to the table. After about 10 minutes, I told DH they had 10 more minutes to send someone over here. Nothing. So, we got up and left. We made a stop at the front to see the manager and told him he could seat some of the many waiting people because there was an empty table over there. He tried to get us to stay, but I was over hungry and too annoyed. He gave us a gift certificate, but we've never been back except for take out.
