Eh... sort of. There is a Harvard Business School case study on this used in law classes you take in business school. 

McDonalds policy was to keep coffee at temp X but many stores, including store in question kept coffee at X+40 (or something like that). WAY too hot for human consumption, intake, etc. The reason the lawsuit stuck was because of this issue and the fact that this happened way more than once. I think I remember reading the cotton in her sweatpants actually melted into her skin it was so hot. 

Additionally, the woman (actually her kids because I believe she was an older lady) tried for years to just get them to cover medical costs and McD's refused. It wasn't until much later that someone with a little more clout picked up her case and made a big deal about it. In the end she still didn't ask for, or get much, if I recall correctly. 

While it seems like a "yeah, duh, stupid!" scenario or a money grab, it was actually far from.
