Last Fall I had a bottle of water...a clear,see-through bottle containing an equally clear fluid...taken from me by security at Hong Kong International Airport.I was *drinking* from it at the time.Amazing,IMO.
Good for them!
Many people wouldn’t stop to think that many drinkable clear liquids may be dangerous, or that drinking may be faked, or that a suicide bomber might not care if it weren’t a “drinkable” one.
