Horse racing is world wide and the jockies must be trustworthy, well behaved and not use verbal abuse.. abusive language as this can effect the outcome of races.

The one's misbehaving ..using abusive language and monkeying around must be kicked out of the sport .

Maybe in their washrooms, restrooms and weighing rooms all jockies should be kept separate and not allowed to talk to each other. Individual washrooms, individual restrooms and one at a time In the weighing room...

In this way jockies can concentrate , psychic up for the race and try harder with the race in hand.
