I always wondered about person who orders hot coffee, then puts the Styrofoam cup between her knees, starts driving and then blames the store for not warning her it was hot after burning herself when she spilled it. Falls in the "can't fix stupid" bucket for me.
The problem with the McD's case is that the coffee wasn't hot like you'd expect - it was scalding hot, far above drinkable temps because management had decided to serve it that hot (180-190F) so that the coffee would still be "piping" when the average commuter would finish their commute. They had been warned hundreds of times about the danger and liability of this policy and still refused to change the temp. That's what got them hit so hard.
Again "hot" coffee, will burn you slightly. The coffee that this woman spilled was hot enough to give her 3rd degree burns
Oh, and she wasn't driving. She was the passenger in a parked car that her grandson was driving and had parked to allow her to fix her coffee.
And of course, they bolded the warning and haven't xhanged much of anything about the coffee. Which goes a long way to explain McD's coffee. (Seriously.. near boiling?)
