yeah i have seen that... my self i'm not a pet/slave/etc. but i know a good friend of mine is (she hates gorean people because of the fact she's into BDSM and wears a collar, though not leashed most othe time, she still gets crap for having a collar on even when its not doing anything its just there around her neck.) into BDSM (not gorean, there is a differnce).
i was more of thinking along the lines of shopping and just casual club places, and was kinda curious.
