AFAIK, water boils at 100°C (212°F) .... at sea level.
or is it 90° ??? no - that's the right angle ........ <img src="images/graemlins/grin.gif" alt="" /> <img src="images/graemlins/grin.gif" alt="" />

Not being a coffe drinker, I guess you make coffe by pouring boiling water on the grounds ... then the temperature just depends on how long you wait before serving that coffe....
or, in restaurants, the setting of the warm-keeping plate on which the pot stands .....

OTOH, maybe you make coffee not with grounds, but with some preparation (no brand names, please !), and then boiling water is not necessary ?????? <img src="images/graemlins/confused.gif" alt="" />

Anyway, I guess you never make coffe (or tea) with lukewarm water.
So, caution is ALWAYS mandatory.
The only responsability I could think of, would be to serve that coffe in an adequat container (resisting that temperature ; permitting a good hold without scorching your hand ; with a cap if it's "to go")
