In some foreign restaurants they pour water for you out of a glass bottle like that. They will leave the bottle with you if you ask. These same restaurants will only give you a single glass of wine not the whole bottle unless you ask for it.
For those wondering how the photo really did happen.
you can put water into any glass you want , I live in Italy and drink water from wine glasses all the time , look just to the right of the boy and you can see Another glass of water in a wine glass
