Well it was super super hot, like you said. It was handed off to some grandma, the lid popped off, and the super hot coffee spilled all over this very old woman's inner thighs. There were pictures.

Old people have notoriously thin skin. Literally. So this hot-ass coffee burns this old woman's thin skin, and I think the resulting burns needed to be fixed via hospital visits & maybe surgery. So yeah it wasn't a frivolous lawsuit.
