Toilets of the World — Toiletological Signage

Neither of these instructional signs are images I took myself, they came from somewhere out on the net. But for those of you needing to instruct people in the use of non-squat toilets, they might be useful. Arabic and Malay. For the Malay one, thanks to Hamachi for the translation:

The nomenclature of "Number 1" and "Number 2" seems to be more than just grade-school euphemisms — it is used by no less a toiletological authority than Sloan!

This was the first of these that I saw, in the public restrooms of a training company in Reston, Virginia, USA.

Water-Saving Dual-Function Handle
UP for #1 (liquid waste)
DOWN for #2 (solid waste)

The green plastic coating on the handle is "to protect against germs", and the sign goes on to courteously ask the reader to "Please take a look at the diagram above and push the handle in the direction which best suits your needs."

This sign is in the toilet compartment on board an overnight National Express bus from Edinburgh to London:
Do not even attempt to pee standing!

This sign was on the grounds of the U.S. Post Office in Chicago, between the Chicago River and the Rush Street entertainment area. I have no idea what it is supposed to mean...

If "curb your dog" means to prevent your dog from defecating on the sidewalk or grass, then what does "do not curb your dog" mean?

Should we force our dogs to defecate on their lawn? (And, while we're at it, any dogs that wander past while we're there?)

Or is this mysterious sign the work of the Anti-Animal-Constipation League, telling us that it's allowed (but not required) for our pets to relieve themselves there?

I was mystified by this sign until Thomas Wensing, an Actual Dutch Architect, saw this page and explained this project by Kees Spanjers:

"I am a Dutch architect, and whilst looking for toilets for one of our projects I happened upon your website. I have an answer to two of your questions. One is about the 'inspection plateau' which you will find on toilets in the Netherlands.i This is not due to the fact that we get our toilets from Germany, as a matter of fact we have quite a few sanitary manufacturers ourselves (Sphinx for instance). It is because we share a similar Teutonic hygienic neurosis and like to inspect our business before we flush it. So, there you have it, we're anal too."

"Secondly, the Latin inscription on the frieze. he apocryphal story is that the way that came about is that the architect of that particular building (it is a refurb of an old prison, btw.), Zaanen, Spanjers CS Architecten were so fed up with the red tape they had to cut during the planning process and grew wary of the vanity of developers and city hall alike that they cheekily decided to put it up there. They figured none of the councillors or dignitaries were clever enough to object to it during the planning process. And they didn't."

"Dear Bob,
I have, in the mean time, done some web research and found the following quote from the architect, who designed the building:
"Roman gates are always carry Latin inscriptions. I chose this particular text, because there had been a lot of hassle in the run-up to the building. There were supporters and detractors, especially locals, no positions in-between. It nearly took fifteen years before the work could start. This is why I figured this to be an apt aphorism."
Translation by me, the original is from agenda.nl, the Dutch text reads:
"Romeinse poorten zijn altijd voorzien van een Latijnse tekst. Ik koos voor deze tekst omdat er nogal wat gehannes is geweest over de bouw van het Max Euweplein. Er waren vooren tegenstanders, vooral buurtbewoners, niets daar tussenin. Het heeft bijna vijftien jaar geduurd voordat de bouw door kon gaan. Ik vond dit spreekwoord daarom toepasselijk."
You can quote me in full in both instances. I do remember quite specifically that it was widely featured in the professional journals at the time, and that the venom of the architect wasn't only directed at the locals. I guess he toned it down a bit when he was interviewed in later years. will not be able to check this in a library any time soon as I am working in the U.K. right now."

Anti-Toiletological Signage

Modern communities sometimes warn of this, in more succinct ways that do not specify the punishments.

For example, Port of Spain, Trinidad & Tobago prohibits wall urination. However, it appears that removing your pants and leaving them there is OK:

On the other hand, see the Belgian toilets page for a case where urination against a church wall is encouraged.
