Thank goodness people are catching on to this. I've always asked for tap water in restaurants but have seen friend's faces contort with shame when I do, as if I'm asking for the waitron to wipe my arse for me. In places like India, China and even Turkey, I'd go for bottled water, but in western Europe and the US, Canada, Oz etc chilled tap water is fine. To me, buying water is the same as throwing money away. And as for this idea about needing to be constantly rehydrated, well, that is baloney. It's base marketing and the drones fall for it. Maybe if your a dipsomaniac, E'd up marathon runner with only one, partially-working kidney, then you do need to take in water constantly. Otherwise, you'll get lots from tea, milk, apples, oranges, even the odd pint of beer. Sheesh. Nero
