similar story,,
there was a bar here out at the end of a pier with no toilet. the guys would just dangle it off the edge. the girls had to travel to the beach to an outhouse. and they complained.
the bar owners then put a bench on the edge so the girls could sit and go out at the bar. no good they said,, no privacy.
so the owner set out some paper bags near the bench they could put over their heads so no one could see who they were, privacy.
i only saw it used once.
