I was confronted by this yesterday at one of the places I work. I'll translate for those who are clueless:
To the person who urinates on the floor
I'm not judging, but if it's impossible for you to urinate standing up without getting it all over the floor, and therefore making everyone else perform gymnastics in order to urinate without stepping in it, not to mention the odor that it causes, why not simply go and urinate sitting down in one of the stalls? This would be TRULY appreciated. Thank you.
I admire the person for the time and energy they put into it and that they even went and found a little picture to go with it. I found it quite funny and it was true, there was urine on the floor when I went to relieve myself there.
