Have you ever had McDonalds coffee? It's not as though we're talking about the stuff you get after it's been through a civet cat's digestive system, where it's scarce and expensive and you really want to extract it at the recommended 200 degrees Fahrenheit to get every last molecule you can of the volatiles out of the beans, so that you aren't wasting your investment.

McDonalds coffee, conversely, is just plain old shit. It's the worst coffee I've ever had, and that is saying quite a lot. If you've ever tasted it, you know that they could brew it at 200, 180, or 140, and it's still going to taste just as godawful. There is absolutely no reason they need to be passing it out the drive-through window at temperatures high enough to peel skin and poach flesh if the half-awake minimum-wage worker who poured it didn't pop the lid on quite right -- or if, while taking the cup and getting it settled into the console, you fail to pay the sort of attention commensurate to a potentially life-threatening process which you probably didn't realize was potentially life-threatening.
