I suppose that if you live in a large house in the the expensive part of Surrey, then you can't really expect to buy cheap petrol locally.
You must be mistaken... I've never heard my caravan be called a "large house" before!

And Ian, surely £1.209 is pure greed and feeding off the car-nuts they knew would be in the area? Especially as I generally find fuel to be considerably cheaper in the Midlands.
