Being in the building trade can sometimes mean that you encounter customers who can no longer afford the completed improvements.
But what you do after finding out makes all the difference.
Well, one builder who wasn’t taking any nonsense from a customer decided he’d knock down his improvements which would cost approximately $30,048 in today's currency.

Back in 2008, a woman had allegedly refused to pay for her new porch improvement, which led to the man to take sweet revenge on her. Check it out:
A then 44-year-old Nigel Gray was hired to install the extension on the home in the UK, as part of a deal with the local council.
Having been contracted to carry out the work, it was up to the tenant to pay for the work, but she didn’t have the spare cash when all had been completed.

That’s when he grabbed his sledgehammer and got back to work.
Rather than constructing, Gray caused utter destruction and demolished it himself.
Speaking to Sky News, he claimed that the tenant had permission from the council to make improvements to the house, but then offered a slew of excuses and missed deadlines for payment.

The Adur District Council went on to confirm that the tenant would have to pay to clear the rubble from her property once the demolition was completed.
Gray pounded on the porch from Anita Dovey's home, taking apart the conservatory one window at a time before removing the French doors too.
The worst part is that the fee had been agreed by both parties before the builder began.
He told the news station: "I'm absolutely gutted to have had to do this because it was such fantastic handiwork but I could not just let this go.

"We just kept on getting a string of excuses and bounced cheques."
When the work was not paid for, Gray revealed that he received consent from the local council to demolish his work.
Gray said: "I have got two businesses and I may have to close my limited company as a result of all this.

"It has been very stressful on my partner and family who have also had to deal with it all."
He estimated that the building work, legal fees, bank charges and lost work cost him about tens of thousands of dollars, which is no small loss.
A spokesman for Adur District Council said: "Council tenants are allowed to make improvements to their home. Unfortunately in this case this private agreement has gone wrong.
"Mrs Dovey will be billed the cost of putting the property back to its original state."
