I refused to fire the main once (as “Chief”) because the owner / operator was about to do something spectacularly stupid. He wanted to depart for Algeria to buy black market diesel without enough on board to make the return journey if the deal went sour. I was certain I’d lost my job, and I probably would have if subsequent events hadn’t proven me right. When we arrived, the price had shifted by two orders of magnitude (“What, you thought I said two cents per liter? Nono, it’s two euros per liter!”), and I was the new hero on board. In that job I was literally worried sick about where to draw the line, how to keep people safe while keeping my job. I lasted less than two years.
Making such dramatic gestures to change established practice and policy is obviously unthinkable.
