Have to have a 'bob each way ' here, I agree in principle with both Reefton and Chimbu.
Some very average 'officials' at time go well beyond their level of competence in enforcing utterly ridiculous instructions....and equally, professionals should not behave in the above described fashion. I understand Jim's annoyance and frustration, if [ as Reefton stated ] the horse concerned had not been prevented from working the matter may not have escalated in this fashion. The horse may have been racing or trialling in a matter of days, to work would have been critical. Faults on both sides.
During my time in racing, in which I have been all my adult working life, I have heard some appalling abuse from supposed professionals, particularly to subordinates,with little done to rein them in. Different if an official is lambasted, though. The hapless stable hand or apprentice has to cop it, often in the birdcage and in front of an audience.
