You could turn the argument around and say that all other coffee
providers serve it at a lower temperature, so the fact that McD's is
the exception shows that they may be doing something unexpected.

If in fact all other coffee providers served it at the lower
temperature. Starbucks doesn't. Dunkin Donuts, whose coffee is
generally quite well regarded, doesn't. Burger King and Wendys
don't. Further, percolators and drip coffee machines and espresso
machines and most of the other kinds of device that one would use at
home to make coffee don't.

There's a difference between brewing temperature and serving
temperature. Coffee should be brewed at 205, but served at no more
than 160 (and 140 is better).

Espresso machines would be a bad comparison, because the coffee cools
off so quickly after coming of the machine.

You make a good point about some of the other fast-food places serving
coffee almost as hot...arguably they would be at fault as well.

When did Starbucks become a "fast food place" and how is it that you know
more about coffee than they do?

I think the best solution would be to serve the coffee somewhat
colder, but use a cup that insulates better so it doesn't cool off as
fast. Personally I drink my coffee in an insulated mug and it keeps
its temperature for hours.

Please identify one brand or type of coffee machine in common use that
chills the coffee to 140 degrees immediately upon completion of brewing.

Also please identify one generally accepted industry standard that supports
your assertion that the ideal serving temperature is 140 degrees.
