I don't mind water from the tap, but it isn't as nice as bottled water...
I really am put off now though, because last night, I had one glass, and that was fine, and then I filled up a second, and started drinking that before bed, and I felt something go into my mouth and down my throat, which, whatever it was I guess came from the cup, and I don't know what it was...
I decided I didn't want to swallow what ever it was with more water from there, so I quickly dived for some orange.
