The thing about the coffee water temperature, you can't get water temperature higher than boiling which is 212F/100C. You shouldn't really use boiling water to brew coffee (as if I was a coffee aficionado) but let's say they did. Then you run it through the ground coffee for the time it takes to brew. Then it's dispensed into a cup, capped off, and handed to the customer. How much heat was released in all that time? iirc, in my coffee brewing experiments, pouring boiling water into coffee grounds immediately reduced the temperature to something like 180F or less and there needed to be some time for brewing though McD's brewing time I'm sure is much shorter in their machine.
Now I'm not saying this customer wasn't injured. The facts are that her skin was scalded to some extent but it could not have been to some "insane temperature".
