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.
I just did a test (for science!) I measured the temperature of instant coffee that I made. Black (just coffee and water) 88C. With sugar, 80C. After I added cream it was 68C.
All of these temperatures are about what you claim to be “above regulation” (please cite this regulation, I suspect you’re just making things up). Millions of people drink instant coffee every day. The temperature being between 80C and 88C is considered normal because it is. When people say “it’s coffee, it’s supposed to hot!” this is what they mean, because people drink coffee at these kinds of temperature everyday.
Now you can go ahead and peer review my experiment, you just need instant coffee, a kettle and a thermometer. Please report back the temperatures you find.
