American courts are weird. You can sue retarded large sums for burning yourself with coffee which now leads to companies throwing all sorts of warnings to cover their asses because God forbid you not explicitly warn some retard not to put silverware in the microwave.
As much as I agree in general principle with that statement, if you're referring to the Stella Liebeck case in particular against McDonald's, that was not an injustice at all. McDonald's seriously fucked up in that particular case, and they deliberately chose to serve coffee at a dangerous temperature. With most coffee, out of ordinary coffee machines, if you accidentally spilled it on yourself, you'd probably have a bit of an ouchie, but you wouldn't be seriously injured.
McDonald's chose to serve it at literally boiling temperatures, and on top of that, at a drive through, where it is completely predictable there will be some spill accidents. It caused massive third degree burns, resulting in the necessity of multiple surgeries, debridements, and incredible decrease in quality of life. This was after McDonald's was well aware of multiple injuries thanks to their choice to do this.
Liebeck wasn't money grubbing. All she asked for at the outset was being reimbursed the cost of her medical expenses. For some reason, McDonald's didn't do what they had usually previously done and just paid them, but chose to be titanic dicks instead. Their lawyers came across as arrogant and insulting, and the resulting verdict was largely because of the jury being incredibly pissed at how they acted.
So when you think about that case and the only thing you really know about it is "someone got millions for spilling coffee on themselves," it looks really bad. But the jury actually got to see the incredibly graphic pictures of horrifying burns and got to watch the repulsive McDonald's lawyers make idiotic arguments as to why it was okay for McDonald's to continue serving boiling hot coffee at their drive throughs, even though they knew this led to dozens of injuries every year, some of them severe.
There are definitely cases where people get ridiculous verdicts in their favor for dumb shit they did to themselves, but
Liebeck v. McDonald's is not one of them.
She deserved every penny she got. IMO, YMMV, OMGWTFBBQ, etc.
