Ah, the old 'I've got a permit from the council' sketch.
Neighbour of mine pulled that one when he dumped a skip in the back lane, blocking my roller shutter door behind which he knew I kept my car.
I explained. politely, his permit did not permit him to block my garage.
This fell on deaf ears, so I rang a mate whose car has a towbar and we dragged the skip out of the way - took a bit of doing even though it was empty.
Next time I saw the neighbour I told him if he did it again, I would have two skips dumped outside his roller shutter door, behind which he keeps his car.
I explained I was aware he was a taxi driver and I would make sure I cost him at least a week of lost takings.
I'm most reluctant to speak to anyone like that, but when I do, I mean it, which I think he grasped.
