From Inet:
I went to a gay club yesterday. The toilets are separated. But the letter is such that it is seen W (W-omen) and S "reversed" (M-en). I wondered for a long time where I should go. As long as I understand the font, a man comes out of a woman (whether a female guy or a brave girl). I am him – where should I go? He says, what is the difference? :D
