This is another "hot coffee" lawsuit, meaning, "customer got life-threatening injuries from lack of safety mechanisms, and the company has convinced the press that it's actually Karen Bitching About Breaking A Fingernail."
Whenever you see these: Remember that even sleazeball ambulance-chaser lawyers are not going to take on mega-corporations like McDonald's or Disney if they don't think they have a real case.
It is, in fact, a crime and a violation of lawyer ethics code - like, the kind that can get them sanctioned or disbarred if it's bad enough - to take on cases that they know are bogus; it's considered a waste of the court's time, which is a waste of public resources. They are literally not allowed to present a case to the court that they know damn well is not a valid claim for damages.
If you drop a coffee cup on your foot, and it is bruised and sore for a week... no lawyer is going to help you sue McDonald's for having slippery coffee cups.
But that's the kind of thing they are trying to claim happened here, tried to claim happened in the Liebeck coffee case. (...Don't google for the images unless you have a strong stomach.)
