Dude, expecting food intended to be handled on receipt to not be hot enough to leave welts on your skin is not insane, it's expecting basic safety precautions out of food prep. This isn't expecting something to be a perfect temperature, it's expecting one that's enough in the range of the use case being sold under it's not literally dangerous to handle, or at least for there to be some kind of indication that, yes, this shit can put you in the emergency room for burns if not handled carefully.
Food delivered via drive-through is not intended to be handled on receipt. Who even
does that? Do you just start digging into the bag immediately?
The lady in the hot coffee case clearly understood that coffee is not traditionally served at a drinkable temperature - coffee snobs say it should be served at 180-185°F - because she didn't try to drink it right away, but instead, was putting cold creamer into it. The main problem is that she for some bizarre reason thought the appropriate place to do this was in her crotch. If you make coffee or tea or even cocoa at home, then apply it directly to the crotch, you will burn yourself. This is a normal outcome of stuffing near-boiling water in your crotch and fiddling with it so that it spills. Hot, steeped drinks are
supposed to be served near boiling. You'll notice that nobody ever gulps down hot coffee straight off the presses either - you blow on it, swill it a bit, sip it gingerly; many people add cold milk. And again, this lady already knew this too. Even if she hadn't, there was
already a warning on the cup.
Look, I'm not saying what happened to the lady didn't suck, but we as a species have to be able to agree that putting liquid which, regardless of the exact temperature, you
know by definition has just been boiled, in a flimsy paper cup, into your lap in order to pull the lid off is foolish and you are probably going to squish the cup and burn yourself. This is why cars have cupholders in the first place.
