I agree. I don't think anyone actually considers actual temperatures, etc. before they handle a cup of coffee in the same way, they just treat all coffee pretty much the same - i.e. 'a cup of coffee is hot, and will hurt me if I spill it on myself, but it won't be serious / cause permanent damage'. It's for this very reason that I think either coffee shouldn't be served at such dangerous temperatures, or it should be served in such a different manner as to make people think - e.g. with some kind of warning attached. But I agree that you shouldn't take this too far; it's why I probably would choose the latter case of action over the former.
