Several years ago a cruise ship out of Miami had a fire in the machinery spaces. There were passengers on the ship who didn't even know there was a fire until they saw the story on the news, before the ship had even docked - and the first thing a number of these people did was call their attorneys on their cell phones to get the lawsuits rolling.
A former co-worker told me once about how his parents were near a hurricane once while on a cruise. Not IN the hurricane- NEAR it. They had bad weather, but nothing near hurricane strength. You guessed it, they were planning to sue. Because according to them the cruise line should have known a hurricane was in the area.
