Charging for water was a pet peeve of mine when I lived in London in the late 90's. When I moved back to the States, to the annoyance of all my friends, I always asked for a glass of tap water when we went out to eat (even if it was the only water available).

Now for some reason, sparkling water is my non-alcoholic beverage of choice (and seltzer water at restaurants that have no idea what I mean when I ask for sparkling water).
