They use some excuse like a blemish on your credit that they did not see before.

When installing new ones in a gut reno, run the finished floor all the way underneath them, so if there is a leak, if flows out and can be seen and fixed, vs. soaking into the subfloor and rotting it.My comment: Most production homebuilders don’t do this, because if anything goes wrong with the flooring during the later stages of construction (tile crack, blemish/scuffing, whatever), it’s much more expensive and time consuming to fix it after the cabinets are installed on top.

But let's just say 80% of them were fabricated, 15% of them were way over dramatized due to taking a close up of a minor blemish and making it look big.  

Any blemishes?

As a regular attendee (and that is my only affiliation) I wholeheartedly agree with her on that.I assume it was an honest mistake but wanted to clear that up before any blemish to Ann's reputation would occur. 

That covers the porcelin, tile and any small cracks or blemishes.
