The water on the other hand...
If I’m a journalist looking to bash a “gay-unfriendly” Olympics I can produce a glass of such water as easily as to take a pee.
I have no evidence to back my theory, it might really be a sand or rust in a water.
I still can’t see it as a problem of such a magnitude. They have to call manager to sort it out or book to another hotel.
