How does this help resolve the contractor's predicament? The work is done and the material can't be returned to the supplier, so unless you've left out an important part of the story, this is just a shock video of an pitiful guy destroying any professional reputation he may have had (not to mention wiping out the possibility of an eventual return on the work he has done!). Does this thug expect potential clients will overlook such outbursts of emotional instability???

Personally, I would sooner give away my work than destroy it over a bill.

I am embarrassed by and for this guy. He clearly needs counseling.
