I think it is amazing you can get third degree burns from a bunch of 80-90 degree coffee dropped in your lap though. I would not have expected that.

80-90 Fahrenheit is barely warm. It was 80-90C, which is just a hair under boiling and will absolutely do serious damage.

That's not serving temperature - that's brewing temperature. You have to work to keep coffee that hot, it's not something that happens passively.

IIRC it was more like 120-130 degrees. McDonalds chose a higher temperature under the assumption it would cool a bit on the trip home, and be a normal temperature by the time you drank it.

Edit - it's in the Wikipedia link:

> Liebeck's attorneys argued that, at 180–190 °F (82–88 °C), McDonald's coffee was defective, and more likely to cause serious injury than coffee served at any other establishment.

In case it's not at the top of anyone's mind, water boils at 212 F / 100 C.
