A customer recently went on holiday. They had a gas leak rather than a water leak.
The guys turned up, dug up much of the road. Knocked on the door to do a gas leak test in the property. I let them in, given that it was the customer who reported a smell of gas. They decided to run a liner in through the existing supply, then discovered that there was a hard 90 degree return. They knocked on the door and asked me to move the car off the drive. I told them that I cannot drive but gave them the car keys. The poor fellow had never driven an automatic. He eventually moved it down the drive. They removed sufficient numbers of block paving. Replaced them and reversersed the car back up the drive.
By the time they had finished, no one would have guessed that anyone had butchered their drive. A year later, I have not noticed any blocks having dropped.
