Some time ago, I wrote a post about some very nice and hygienic WCs in Amsterdam. Aitor posted a nice post about the flat-bottom WCs you can find in Germany or the Netherlands. He got "moved" in meneame.com and got thousands of visits in a couple days!
When I was in Berlin, in the toilet in the hostel we slept at, there were some instructions how to use this kind of toilets... What i wonder is, is it necessary to be so explicit? hehe... Judge by yourselves!
What I like the most about these "instructions" is the attitude of the figure on the left. The cap is a key element... The guy spilling out the toilet has his cap backwards, whereas the other guy has is in a more socially accepted forward position XD
