There should be an invisible 2m around the officials that no player should cross unless by accident (eg running at full pelt, but even then they should be seen to make every effort to avoid collision, perhaps put their hands behind their backs or down their shorts so that they avoid any flailing arms). The 2m should be extended if any player has very long arms, legs or massive beer belly.
However, officials can cross the 2m themselves, but only to talk in a gruff voice. They must never smile, wink or have any normal conversation with any player or coach.
After they retire from officialdom, they may have 'normal' contact with ex players etc, but not with any current players or coaches
1 year after they retire, they can speak to anyone - but never bring the game into disrepute by discussing present officials - gossip or facts
After 2 years they can marry them if they like - then the 2m will naturally come back, along with the long silences, stern voices, and making every effort to avoid contact
Quality of the highest order, with this kind of apptitude you are bound for Red Hall as an exec with an RFL number plate.
And so the future begins.....
