Look, the Dartford Crossing fine is a classic “gah, I’m an idiot” moment. But it’s also a reminder that you survived a trip around London without losing your mind. That’s a win. Pat yourself on the back.
Set up that Auto Pay account. And next time you cross, give a little salute to the toll gantry. It’s not your enemy. It’s just a very expensive, very forgetful friend who needs you to pay attention. Or, you know, £35 worth of attention.
