In W Africa (which I'm always harping on about) you have to get used to people just using the roadside or a handy tree in full view. No-one thinks anything of it, as there are no public lavatories to be found. I certainly didn't mind. DMcG is quite right: it's just cultural habits.

I had to smile about the 'Genital Inspectors'. Just imagine exposing oneself at the entrance to a toilet in order to gain lawful entry. It would be like an episode of Monty Python!
