I think this says more about the secretary than it does about Jordan and Gary. Why would somebody think that a co-worker could be gay because he was sat with someone else who was wearing 'non-standard' attire? Does this mean that a man walking down a street, who donates some spare change to a busker suddenly becomes a musician? The faulty logic is the same. Guilt by association.

Homosexuality is no longer illegal in the UK, but it is illegal to discriminate on those grounds. If it were me I would ask her a very probing question of a very intimate nature. When she objects (as she will), I would come back with "But you think it is alright to ask me about my sexuality". No official action is taken, but she is made aware that her behaviour and actions are unacceptable.

Like most things in life (Health and Safety; Good working practises; relationships) People Don't Think. If people stopped and thought first they wouldn't step in front of the moving car; burn themselves to death; take the wrong pills or ask the unnecessary hurtful questions. Had she thought first, she would have seen that it was none of her business on any level and anyway her employer did not pay her to stand around gossipping all day.
