This just crossed the wire, from Roswell, Ga.:

ROSWELL, Ga., April 26 /PRNewswire/ -- Janitors of America take note.

Despite your best efforts, most people who use public bathrooms are performing
their own personal maintenance before using the facilities.

In a survey of 1,015 adults conducted by Opinion Research Corporation for
Kimberly-Clark Professional, nearly three quarters of respondents said they
conduct some kind of maintenance before using a public restroom, such as
wiping off a seat cover or flushing the toilet. Nearly nine in ten of those
who do so said they use supplies that are already in the restroom - a seat
cover, toilet paper or a paper towel.

At last: a poll where Americans aren't evenly divided. (Insert "weapons of mass destruction" crack here.)
