The Antifragile Chaos Monkey
Just don't drink it!
You are right of course but I think it's more the fault of the hotel or the caterer. So you should probably direct your ire to them.I think I have seen once in a while where they use a Sterno fire thingie under the water to keep it near boiling. But you're right, usually they just put out a bin of "hot water" and that is disgusting.
As in all cases, I prefer to direct my ire at you.
