A few years ago the family and I were at a ren-faire where we were performing. Our day went as usual. Then I needed to pee....
And as is common when one has on a bodice/corset, and two "blessed with yardage" floor length skirts, going to the bathroom can be quite an accomplishment. I have long held that a woman in renaissance costuming has full rights to use a handicapped stall/porta potty. Because if wearing a bodice/corset and yards of fabric in her skirts, with maybe a hoop, isn't being handicapped in the arena of toilet use, I don't know what is!
So I used the handicapped porta potty, straightened my clothing, and looked up at the sanitizer dispenser...
On it I read, "Please apply to clean, dry hands."........

I laughed uproriously. Because, if my hands were clean and dry, why would I need sanitizer?!

Ah! The sign must be for the great unwashed masses! ; D
