I saw this on a train yesterday, sorry for the flash ruining the English text, but I was trying not to miss my stop at the time as well!
For the non English:
Environmental Friendly Toilet:
for toilet paper use only.
For other materials please use the wastebin to prevent the toilet from becoming blocked.
I do not want to empty that bin at the end of the day! Or as someone I knew pointed out - this explains the mess at the stations!
And yes Cass - I think this is a perfect example of why you should never underestimate the need for professional writers!
