Filthy jacks. Hovering over the gross toilet seat, thanking god that there's is still some loo roll left (because there usually isn't). Getting the rock out of there as soon as you've tinkled.
A new campaign from an Italian HIV charity uses QR codes printed on bog roll to bring you to their site where they ask if you worry about safe sex as much as you worry about catching something horrible from a public toilet.
