Driven to crime

Some service stations in Sydney are employing security guards to prevent petrol theft. The problem has been steadily increasing with the cost of fuel - and last week it was reported that at least 30 people a day are failing to pay before driving away from the pump. And now that petrol is so expensive ($1.40 a litre or thereabouts) - the cost can add up. Surely there could be a pay at the pump system where the user had to insert their card (pre-paid or credit) to start the petrol flow? (You read it here first! ... or maybe not. Thanks Lizzie.)
