In my opinion Kymmy the Saudi establishment uses the fraternisation excuse in a lot of cases, like this, purley to keep women out of the work place.
From the point of view of the Saudi male they seem quite content to keep "their" women subjugated, even enlightened Saudi men are soon put down by the religious police when suggesting maybe that women can drive or god forbid even vote.
Of course all these rules for women are couched in the catch all statement, "we are looking after our woman",

in reality they are frightened of losing the upper hand.
