No worries.
What about the 60s-early80s when small building jobs around the house could be "negotiated' between home-owner and tradesman(aka "cashies").
Then in 1983 Big Brother" introduced the PPS system then later the GST?
Although, some people who had work during that era are now rueing the fact that there was no building code to protect them from poor workmanship.

Cheers.
