This is contradicted by wikipedia, which says McDonalds continues to heat their coffee that hot, and that Starbucks and other coffee shops do as well:

https://en.wikipedia.org/wiki/Liebeck_v._McDonald%27s_Restau...

> Since Liebeck, McDonald's has not reduced the service temperature of its coffee. McDonald's current policy is to serve coffee at 176–194 °F (80–90 °C),[40] relying on more sternly worded warnings on cups made of rigid foam to avoid future liability, though it continues to face lawsuits over hot coffee.[40][41] The Specialty Coffee Association of America supports improved packaging methods rather than lowering the temperature at which coffee is served. The association has successfully aided the defense of subsequent coffee burn cases.[41] Similarly, as of 2004, Starbucks sells coffee at 175–185 °F (79–85 °C), and the executive director of the Specialty Coffee Association of America reported that the standard serving temperature is 160–185 °F (71–85 °C).[citation needed]

This case seems to have myths inside myths. The first order myth is that the lawsuit was bogus. But there's a second order myth, that the temperature of the coffee was unusually hot and they've since changed this. What is true is that the coffee was hot enough to cause severe third degree burns, requiring skin grafts, and that McDonald's coffee cups at that time were prone to spontaneous collapse. But the coffee was not unusually hot; coffee hot enough to cause those kind of burns is the norm. In fact even coffee substantially cooler than that can cause third degree burns, particularly with children and the elderly. Look up scald charts, 140 F / 60 C can cause third degree burns with only 5 seconds of exposure.

There's a CTO here who used to seal McD's grease drums at night by jumping on them. Son of store owner.

"Dosing furnaces are closed holding furnaces with a spout for direct metal delivery. They are used to dispense an accurate amount of molten metal into the die casting machine. The advantage of dosing furnaces is that because it is closed, it minimizes heat loss and protects the molten metal from excessive oxidation."

I did tech at a mechanical/electrical/plumbing contractor called US Engineering in KC. The union (unions?) and Corporate worked pretty well together, because they had to. Aggressive subcontractor bidding means you only get a few percentage points of profit on each job, the unions fight to get their fair share knowing that if they fight too hard they make the company brittle and they don't want the company to fold, indeed it was kind of shocking to hear people taking some pride (even in jest) at making the CEO and his family some cash.

But the biggest thing was, Believe In Zero. Huge push, lots of concerns that all of the new hires in new regions working on data centers did not understand this long-held cultural expectation. It's to believe in zero “unsafe behaviors,” things like turning with one foot when you get off a ladder (instead of planting both feet on the ground and then turning). Even if “Believe In Zero” was the corporate side, the unions were committed to “yeah that's what we do” and typical welders would remind me that they are working with thousand pound plumbing assemblies, cutters that need to slice these massive pipes open, and of course day-in-day-out they are going to be staring at the plasma of a welding torch melting this stuff back together—“all any of us want to do is to have some pride in our work, get a fair paycheck, and get home safe and healthy,” they'd say.

Why would Corporate care, why would the unions push so hard for how you step off of a ladder? Because if you roll your ankle or yank the ladder towards you, could create an injury, that requires paperwork for OSHA, then the insurance company will look at that paperwork to try and argue that they should get more money because you are not a five star super-safe workplace, even if they are not paying that much for the actual incidents. And when your margin is only a couple of percentage points, you can't be spending half of it on insurance.

So they did. Heck even I got into it. One thing I did to “Believe In Zero” was to cover up all of the exposed nails or splintery plywood in the corner where we stored soda. Sure “no reasonable person is going to run their hand across these surfaces”, but hey, you never know, maybe someone spills a coffee and someone else slips on it, if it's just 10 minutes for me to fix it now, and I can be thinking about how I want to structure a module while I am doing it, why leave it?
