You must use tap water! If you live in Paris, France that is.
Tap water is just fine.. it tastes the same as Dasani or Aquafina or Crystal Springs... Wait... doesn't Evian come from France?
Yet another example of the government bailing out a failing industry. People turn to bottled water not just because of quality but of convenience. They don't exactly let me use the tap at the local gas station, you know. And.. uh.. given the state of the bathrooms, I really wouldn't want to use the tap at the local gas station.
