I've been wracking my memory but can't remember where I saw it. I thought it might have been either the Old Boomerangers or Skiathos Lovers Forums, but when I tried the search box it didn't come up with anything. Bob
Unless somebody has torn it down, there's a prominent enough notice right above the tap at the BS4 one, can't miss it. Presumably the English is not sufficiently direct enough for people to understand when it says drinking only it also means not for washing your (Word Deleted) feet. We take an EMPTY bottle to the beach and fill it with sea water to wash our feet.
Just read this thread and I'm sure I've either been told by a local (or read on a forum) that although the spring water is perfectly good for drinking it can upset our delicate 'foreign' tummies as it has a higher mineral content than we're used to. So, that's the reason you could get an upset stomach if you drink it! It's a bit rude to wash your feet at the drinking fountains!!!!!!!
