And there's respecting of guests' religion.

What if the Hindus had said "we are vegans, please don't serve us meat" - probably reasonable enough, although I seem to recall some rightwingers getting angry about some other occasion where only vegetarian food was to be served.

Yeah, as a host I'd be fine with meeting their dietary restrictions; but would refuse their with staff gender restrictions. Somehow the management company didn't know where this acceptability border lied.
