Except it's not supposed to be hot enough to cause third-degree burns. The entire event is horribly mischaracterized.
From https://www.caoc.org/?pg=facts
> Mrs. Liebeck was not driving when her coffee spilled, nor was the car she was in moving. She was the passenger in a car that was stopped in the parking lot of the McDonald’s where she bought the coffee. She had the cup between her knees while removing the lid to add cream and sugar when the cup tipped over and spilled the entire contents on her lap.
> The coffee was not just “hot,” but dangerously hot. McDonald’s corporate policy was to serve it at a temperature that could cause serious burns in seconds. Mrs. Liebeck’s injuries were far from frivolous. She was wearing sweatpants that absorbed the coffee and kept it against her skin. She suffered third-degree burns (the most serious kind) and required skin grafts on her inner thighs and elsewhere.
