Meanwhile, retailers have reported a surge in verbal abuse towards forecourt staff by drivers angry at pump prices.
Jack Cousens, head of roads policy at the AA, said: “With Wimbledon well under way, drivers may be forgiven for borrowing the iconic rant from John McEnroe as they pull up to the pump – ‘You cannot be serious!’.
“However, with some reports of aggressive behaviour towards forecourt staff, we urge people to channel the zen-like mentality of Roger Federer when refuelling and not abuse staff.
“It is not their fault, which is why the AA is directly challenging the Government, retailers and the Competition and Markets Authority (CMA) to find a quick and effective solution.”
