What Exactly Happened In This Dublin Café Toilet To Make Them Post This Seriously Intense Sign?

  Sometimes when you see a sign posted in a public place, you can but wonder: "What on earth happened for them to have deemed this necessary?" And this oddly intense sign, spotted in Love Supreme Coffee in Stoneybatter begs that very question. No wood? No METAL? AN ALARM ON THE TOILET?
