I have a cousin in Townsville who does a fair amount of crabbing and is one of those guys who sticks to the rules with measuring his crabs.
He was pulled over by the the Inspector who promptly pulled out a Micrometer from his pocket and commenced measuring the shell via that method.
When my cousin objected to this and checked them against his standard plastic issue measure whereby they all passed the test, the up-himself-with-authority- Inspector advised that he would check them any way he wanted and promptly hit him with a $200 fine because - wait for it - the Micrometer showed a half to one mill discrepency!!!!
Even when advised of the obvious fact that they were OK via the plassie template, the ######## on the other side grunted about "regs are regs" and roared off!
I have found most Inspectors pretty reasonable but like most people in uniforms, it only takes one or two galahs to spoli the record!
Maybe some NQ members can confirm or deny this sort of thing?
