There are no signs to say they'd removed the toll booths on the Dartford bridge.
I had change ready and kept looking for the signs to say how much it was. Arrived at where the booths should be I guessed they must have moved them to the other side for some reason. No explanation, THEN a sign put up by some idiot who said I had to pay on-line within the next day I think.
That sign should appear while I had the choice to go another way.
When I got home a week later I paid on line but the bastards still sent a nasty letter.
I'll be sure not to use the 'ing M25 again!
