It's ridiculous? No. It's true. I don't like straight water. I haven't been conned, I don't prefer one type of straight water over another, I don't have any reluctance to use tap water for cooking or preparing drinks. I just don't like the taste of plain water. I've sampled it from all over North America, everywhere from municipal water supplies in Florida to straight out of streams in Alaska, and it is not something I want to drink unless I have absolutely no other choice.
And, since I am in the First World, I do have a choice.
