Is this common for jocks agents?

It seems like a pretty steep fine.

Jockey Agent VIC STAUFFER, pursuant to California Horse Racing Board rule #1530 (Cases Not Covered by Rules and Regulations), is fined FIVE HUNDRED DOLLARS*($500.00) for failure to handle his business in a proper manner-failure to honor his call.
*Rule #1532. Fine shall be paid to the Paymaster within
seven calendar days from the date of this ruling, or the
license of the person upon whom the fine has been imposed
shall be suspended.
