Hamburg's St. Pauli's is a case-in-point. Some twenty million patrons prowl the pubs and other portals of carnal pleasures peeing on walls and putrefying the place.
But it's 'pee-back-time-baby.'
Hamburg is spraying the walls with Ultra-Ever Dry a super-hydrophobic, oleophobic nano-coating, which is so water repellent the excreta is forcefully foisted backward at a forty-five-degree angle.
One shoe soaking should be sufficient, right Siegfried?
