This sign was on the inside of a toilet cubicle door at the Scientia building at UNSW. I've never seen a warning anything like this anywhere -- in all the toilets I've visited around the globe. That suggests to me that some incident had occurred at this venue prompting the need to warn future users of this fine latrine.
But I was struck by the pictures, presumably intended for those who could not read English (because the written warning is quite clear and needs no illustration). The pictures suggest what position one should not adopt, but do not say why. It could quite easily be taken as "if this is how you normally use a toilet, you cannot use this one". In fact, there are many possible interpretations, most of which would not be helpful.
If the intention of the sign is to reach out to non-readers of English, it has done so in a rather culturally insensitive way (which may also lead to disasters other than broken toilets!)
