People always talk about the McDonald's case without knowing the facts. McDonalds over a ten year period received over 700 complaints that its coffee was too hot, and many people complained of third degree burns. The restaurant ignored its customers concerns.
Home coffee is usually brewed from a machine at 135 degrees. It is typically served in restaurants at 155 to 175 degrees.
Mcdonalds was serving coffee at 185 to 190 degrees, which is not the industry standard and is hot enough to give somebody a third degree burns.
I think most people might expect to burn themselves if they put a coffee cup between their legs and the lid came off, but I doubt most people would think the burns would be so bad you end up in the hospital for days and need skin grafts.
Further, the lady was only sung for like 20 grand to cover hospital expenses. It isn't her fault fault McDonalds didn't just pay up.
700 complaints over a 10 year period is amazingly LOW considering how many people McDonald's serves every day.
This ruling was overturned for good reason: it would've set a bad precedent and anyone who spilled coffee or other hot drink on themselves could've sued McDonald's (or anyone else) for millions.
As for the coffee's temperature, any self-respecting coffee drinker will tell you that you need to brew coffee at around 200F to make good coffee. The fact that most people buy crappy coffee machines at home doesn't mean that McDonald's was in the wrong.
Bottom line: take responsibility for your own actions and stop dragging this country down with silly lawsuits.
