Jesus you are dumb.
If you knew they were hot enough to burn his mouth, offered him the marshmallow for his immediate consumption, and he burned his mouth, you would be at fault for FAILING to meet a duty to inform him of the nature of the marshmallow.
The stupidity in this thread is astounding. It revolves around who had the knowledge, and was the person harmed operating reasonably and was their lack of knowledge reasonable. When offered coffee is it reasonable to assume that spilling it can cause the burns she received in that severity? Maybe a little burning is probably reasonable, but 3rd degree burns from coffee? C'mon, don't be ridiculous.
I would reasonably expect very serious burn from spilling coffee on myself. I would also reasonably expect that as I age my skin will not be as protective as it once was. I would also reasonably expect that I, Me, Mine, would be responsible in my actions around dangerous things and at all other times.
Also, you are treating this as if it was the first time this woman ever went to McDonald's I would reasonably expect that nearly everyone has been to McDonald's. I would reasonably expect that nearly anyone who has ordered coffee at McDonald's has ordered coffee at McDonald's before.
I don't know about you, but I find warning labels for the obvious, tedious and insulting.
This object is heavy. If it falls on you, you could be injured. Ya don't say...
This object has grindy parts that can turn your soft fleshy bits and bones into hamburger. Don't put your soft fleshy parts or bones into the grindy parts. Whoa! Dude I was so going to stick my hand in there before I read this very informative and life-saving label (that cost $4,000,000 in attorney's fees, regulatory fees, printing and application, as well as our internal compliance department's salaries). I mean thank god legislatures look at these scenarios and draft legislation, and hire regulators and form new branches of government, and spend all our money protecting the very stupidest of the stupid from themselves instead of wasting their time on trivial matters like the fact that our country isn't even owned by us anymore (in the sense you don't own your car or house) and that our kids won't be able to pay the bill and the house is going to get foreclosed on, or that corporations are treated as people when that serves their bottom line and headless guiltless entities when that serves them, and that people are treated as cattle who's only legal function is to serve corporations. I mean they could waste their time figuring out how to extricate us from an unwinnable war against a faceless nameless enemy, that we got ourselves into in the first place with our delightfully negligent, greedy, and ethicless foreign policy, but they focus on what's important, staying elected to protect us from ourselves.
Or maybe that's the whole idea...
