This is completely out of touch with the realities of modern day commercial shipping.
the complaint in the Seafarer Happiness Index that they are being supplied substandard food by unscrupulous chandlers is not entirely fair. It’s the cook’s responsibility to inspect food coming from the chandler, and the master’s responsibility to make sure bad food is rejected and sent back
It does happen from time to time that an error is spotted during loading/storing but given the tempo of cargo operations and quick turnaround times it’s not something that is going to happen on a regular basis.
Better advice for a yachtsman maybe then large commercial ships.
