About my mother...

Choong's mother is visiting him, from Beijing. His presence in Stufital bar is proof enough that the ban on Chinese doesn't apply to men. But can he bring the old lady (she's 73) in for a quiet drink? Of course your mother is welcome sir! But this raises new questions. The ban can't be simply racist, since Choong is unbanned. And it can't be simply sexist, or there would be no Filipinas allowed.
