Not here really. I go to pretty kinky parties and I often find myself on the metro with other partygoers. One time pretty recently there was fellow partygoer (unknown to me but clearly from the same party) who even had her boobs out in the metro (at 4am) and no comments or even weird looks were made. It made me happy seeing the tolerance and diversity (and, admittedly, the boobs too ;) ). Nobody was being weird or trying to sneak a photo or anything.
Though strangely enough a friend of mine was told off by security for taking off her heels while sitting down (they hurt a bit) but at the same time ignoring the boobs girl altogether lol.
