In another thread excelsior and I were having a bit of repartee on this subject. Both of us are irritated by this practice. The tiny imported bottles of still water in expensive restaurants in Sao Paulo were and excelsior objection, and I can add dozens of places around the world. There are a few excellent places that serve filtered tap water and do not charge extra for that. Maybe we can applaud those here. There are others like Bistro da Escola in Rio de Janeiro that offer imported still water, Panna in this case, and let you pay $20 or more for the privilege of drinking the stuff. At the other extreme come those places such as Olympe in Rio again, where they'll serve you filtered tap water without noticeable objection. So, please offer your views.
