You know I love signs. Many of the best ones express one person’s frustration at something that’s beyond his or her control. More often than you’d think, this relates to another person’s (or dog’s) bodily functions. I get such perverse pleasure when I walk into a new (to me) public washroom and see a sign like this. I can’t help but wonder how long and often the sign-writer has had to put up with the problem before going back to his desk, selecting a 44-point font in Word, printing out a shaming notice, and taping it up outside the stalls. But I’m even more curious about whether shaming notices actually work. Anecdotal evidence would say that they don’t, but I can’t tell you how many times I’ve wanted to track down the person who made one of these signs and ask if it generated a concrete result beyond the short-term satisfaction of calling someone out for anti-social behaviour.
