We’ve seen a lot of toilets along the highways and byways while making the 19-hour drive from Arkansas to Anna Maria Island, Florida, including a couple of special ones in the middle of the night on Alabama back roads (it was a shortcut).

I told the woman encased in her plastic booth at a Shell station off I-75 in northern Florida that the men’s room was out of paper towel: she sneered.

But the best sign came from the toilets at the Southbank splash park and playground in Brisbane, Australia, where people apparently have a unique approach to using the facilities.
