Cleanliness is NOT Next to Godliness
by Chris MacDonald
But I guess dishwashing is not welcome everywhere. This sign is in a public bathroom in Lieber State Recreation Area near Cagles Mill (or Cataract) Lake in Southern Indiana. (My guess is that food waste clogs the bathroom sink drains, or that people doing dishes take up more than their fair share of sink time.)
p.s., Thanks to Abe Schwab for the photo.
