There is a wonderful, fairly old, episode of COME DINE WITH ME. In this, one of the 'contestants' is a very smug, self=opinionated wine 'expert'. Anyway, one of the other contestants was hosting her dinner party and had put out - as well as wines - bottled water. this ran out, and the guests asked for more. So she went into her kitchen (in front of the cameras), found an attractive empty decanter and filled that from her kitchen tap and took it out to her guests. the wine 'expert', tasted this and then asked what it was as he stated, it was one of the very best tasting water he had ever drunk!!!!!
