It drives me nuts, we have some of the best tap water here. There are stricter guidelines for tap water than they have for bottled water, but i see so many people buying shopping carts woth of plastic garbage with crappier, more expensive water inside.

CO2 saturators are cheap. I love carbonated water and all I buy is a gas bottle fill every two months or so for 15 euro, on top of that I don’t need to carry any heavy bottles upstairs.
