During the trial it was revealed that McDonald’s knew that heating their coffee to this temperature would be dangerous, but they did it anyways because it would save them money. When you serve coffee that is too hot to drink, it will take much longer for a person to drink their coffee, which means that McDonald’s will not have to give out as many free refills of coffee. This policy by the fast food chain is the reason the jury awarded $2.7 million dollars in punitive damages in the McDonald's hot coffee case. Punitive damages are meant to punish the defendant for their inappropriate business practice.
People love narratives that are simple and have an easy to understand moral to them even if they're absolutely wrong. In this case, the narrative is that she asked for hot coffee and got hot coffee, and the moral is that people are greedy and stupid and you have to protect yourself from them. I've often found that one well-constructed point can blow these narratives up though. I was talking with my dad about this particular case, he's a big "gotta do something about these frivolous lawsuits" guy because he used to own a business that was adjacent to real estate and real estate is probably the most litigated business in America. I'm a big "frivolous lawsuits is a term exploitative industries use to get people excited to give up their rights" guy, so we were at loggerheads about this one. Eventually I was like "Have you ever spilled coffee? When you did, who paid for your skin grafts?" Turns out that when crafting their narrative about how she was "suing them for giving her what she asked for", the industry lobby left out the part where she had to spend 8 days in the hospital and have multiple reconstructive surgeries.
