I agree that some here could have used a little more tact in their reply. But they were right to not simply throw another contractor under the bus without hearing his side of the story.
"The first to state his case seems right, Until the other party comes and cross-examines him." - King Solomon.
Likely from many years of experience, many of the 'ole boys' here know when something doesn't quite seem right.
I find it an interesting coincidence that most of those who are agreeing wholeheartedly with Tessa's narrative and expectations, seem to have less time under their belts as pressure washers and business owners. The conclusions she has made appear obvious at first glance. They're standards that all businesses should striving to meet. But the problem with simply agreeing with those conclusions is that it makes us all party to whatever she has planned for our testimony.
Again, I'll quote the wise king:
"13 When anyone replies to a matter before he hears the facts,It is foolish and humiliating."
That implies hearing the facts from both sides of the case.
