My father-in-law had a craftsman at home in his garage to lay tiles. However, he belongs to the old school who doesn't like to complain. I have put myself in a bit of an uncomfortable position where we have differing opinions on how work should be done. I'm attaching a picture of the work and wanted to check with you if you would have paid for the work without complaining.
I would have complained. Admittedly, it was a pretty cool solution, but it's certainly unconventional and impractical. If the craftsman had made such a solution on his own, I would have questioned it. How long will it be before someone steps into the hole and falls?
