How to explain the real cause of high petrol prices to the public

Cazzy Jones has a fantastic idea to bring home to the public who is to blame for high petrol prices:

'Just imagine a dual till system on the forecourt, where the driver goes to the first till and pays £28 for the cost of the fuel and the retailer’s profit margin, and is then channelled to the second till, coming face to face with a bureaucrat who tells him: “Because you have spent money filling your car up, you must now give more money to the government.” “How much?” “£52.” “But that’s almost twice as much as what I’ve just paid the garage!” “Tough. Pay up and shut up.”'
