Some of the signs in very "designer" places are getting a bit too subtle, in placement or symbol.
It was said that following the tsunami some Japanese ladies were just too embarrassed to "go" without the comforting sound effects of their hi-tec loos to camouflage the noise
I can sympathise with that. Im VERY particular about where I "go". NEVER in a public toilet, and only as a last resort at a relatives house, never a friend's.
I dont think Im alone in this either.
I used to find it difficult, but after WWOOFing for a year, living in the woods with communal hole-in-the-ground loos (the walls and doors were sacking) and in a straw bale house with an outside straw bale that you peed on!
, then living in a static with no services whatsoever - after that, I found I lost my embarrassment and can now go pretty much anywhere... between the front and back doors of the car in a layby, for one. One of the people I met WWOOFing did a lot of festivals etc; she maintained that the best way was to wear a big skirt - "You can squat down, your skirt reaches the ground all around you, no-one knows what you're doing under there", she'd say!
Mind, I'm less keen on peeing in the woods after I came home with a little blood-sucking lodger...
