In reply to toad:
Agreed, though Councils are as bad.
Best P&D system I have encountered - pay and display in Ambleside. Press a button for how long, tap your contactless card, sorted. No faff with change, apps, phone calls or any such nonsense.
Even better, pay on exit (camera enforced) using the same system. Drive in, on the way out enter your reg number, tap your card, done. If you fail to do so before leaving, fine arrives in the post automatically.
