It turns out there's a lot more to the story. First of all, the hot coffee wasn't just uncomfortable and embarrassing, it gave her third degree burns over six percent of her body, which required fucking skin grafts. You can see the burns yourself if you're not squeamish.
Secondly, coffee served at that temperature (180 to 190 degrees Fahrenheit) will give a person third-degree burns in two to seven seconds, while home-coffee brewers normally serve coffee at much lower temperatures (130 two 140 degrees) which won't immediately burn you. Yes, Starbucks and other joints do serve coffee at the hotter temperatures -- because some customers prefer it -- but then again, they get sued for it also. Thirdly, she attempted to settle for $20,000 at one point, and McDonald's refused, which is when she started getting cranky.
"Not my problem."
You may have heard that she got millions of dollars, when the final award was $640,000. Then from that you take out the medical bills (hint: skin grafts aren't cheap).
But she has to take some responsibility, right? She may not have been driving, but she was trying to open the lid in her lap so she could add cream and sugar. That's kind of careless, isn't it? Why couldn't the jury see that?
