On a Post long ago (I cannot trace it now), I told of a famous "Daily Mirror" cartoon from WWII. The scene is set in mid-Atlantic. Against a darkening sky, over on the horizon, a torpedoed, burning tanker sinks.
In the foreground, spreadeagled on a piece of floating wreckage, soaked in fuel oil, a lone merchant seaman, lies dead or dying.
The Caption ?....."The Price of Petrol will be increased by one half-penny per gallon from midnight tonight".
Suddenly, "knocking off" a gallon of aircraft or MT fuel for your car didn't seem such a good idea, after all.
