both Surrey and West Sussex (and many more besides, I'm sure) have contracts that say the roadmenders should fill holes that they have been told about, and are a certain depth, and leave anything else. I've seen this in action - and the result is that the slightly smaller hole gets bigger, and they have to come back to fill it. How is that sensible?

sometimes it's easier to tell them which part of the road doesn't need filling
