I think the point of this sign is that you're not allowed to
defecate outside, but I also read it to mean that there's no
charge for defecation.
Any Tour rider will tell you that staying in a town, as opposed to
camping out in the bush, was a mixed blessing. On the one
hand, you've got restaurants and running water and laundry
facilities and pharmacies and Coca-Cola. On the other
hand: Sudanese public toilet.
The phrase Sudanese public toilet
should strike terror
into the heart of the most courageous of men and women. It
should strike terror into their hearts in the same way that
"nuclear launch failure" and "President Schwarzenegger"
I'm not kidding when I say that many of us preferred to camp in
the middle of nowhere, digging a hole in the dirt, than to stay in
a place where your shower and your toilet were the same
thing. You don't want to kiss anybody who disagrees.
