The article does mention pay at pump technology:
Parekh says officers “take the view that this is a totally preventable crime”, telling him he should install prepaid pumps to stop thefts. This, he says, is a non-starter because “the whole trade has to move to that system, otherwise people will get annoyed and go elsewhere”.
He would lose business to other petroleum stations unless everyone does it.
What is shocking is that the police don’t treat it as a crime, even though making off without payment is in the Theft Act 1978. They say he should sue in the civil courts, but criminals are cloning number plates and innocent people are getting summonsed.
It’s like shoplifting. The police don’t have enough resources. It’s considered a low level crime and the victims are usually massive supermarkets or petrol companies.
Personally I think we need to crack down hard on petty crime to prevent larger crime becoming a problem.
