I am currently studying the McDonald's case in a business law course I'm taking. I also was "duped" by the media campaign on this and thought the coffee case was crazy; until I actually read what happened.
Yes, McDonald's serves coffee about 40 degrees hotter than industry standards. Hot enough that if it gets on your skin you will suffer third degree burns. That's a full burn through every layer of your skin down to the muscle. The customer suffered these burns all over her thighs and groin area. Had she gone to Dunkin Donuts and had the same thing happened, she would have merely scalded the top layer of skin. She also asked McDonald's to pay her $20,000 medical bills. They scoffed at her. She then went to get her $20,000 through a lawyer and the courts then assigned punitive damages in the millions for McDonald's behavior and setting their coffee temps way outside the norm for coffee. The customer was assigned 20% of the blame (adding creamer to coffee while sitting in her car) and had her award reduced by that much. After it was all done, they went on a media campaign smear to discredit the customer.
