I was at the PI (Philippine) Consulate in San Fransico and couldn’t resist taking a picture of this sign that was posted to the left of the toilet, just read the 1st two lines and I guaratee you’ll laugh… Image is below.
If you don’t get it, then take a look at this picture and I think you’ll associate the request. BTW, this is a toilet in China, the sign above was posted in a US bathroom on what “NOT” to do with the western toilet.
