Off topic for a moment because you almost sound sympathetic to that asinine lawsuit.
Everything you just explained goes to further prove the idiocy that is our legal system in America. I've (unfortunately) drank many cups of McDonald's coffee in my day, both before and after the lawsuit (along with millions of other people) and we all managed to not get 3rd degree burns and sue McDonalds. The simple fact that we can even sue for garbage like that has created what is probably the most litigious and entitled society on earth.
