Certainly much bigger person than me mate. The act of robbing Peter to pay Paul is still a low act. At the end of the day he took your cash on a whim that maybe he could finish your boat. That in itself would be enough to get violent. Your life has certainly given you some serious fuse length.
Hope all works out for the best mate.
About bloody time this industry had some serious regulation to protect the general public. Enough is enough!
Cheers
