Could you read a little more about that case?
1) McDonald's had burned hundreds of people by that point, as the plaintiff's lawyer said in "Hot Coffee", "they were on notice." They served it that hot IIRC because it would stay hot slightly longer, even though lowering the serving temperature a tiny amount reduced burning disproportionately and would have prevented that and hundreds of other accidents.
2) The server didn't actually attach the lid to the cup.
3) She had horrible burns, 3rd degree.
4) McDonald's received an offer to pay for her ~$10,000 medical expenses, and counter-offered $600.
5) This was an old lady who had never sued anyone in her life.
6) She ultimately gave up on life in her old age because of the shaming.
"Hot Coffee" opened my eyes about the whole matter. I suggest you watch it.
