Yeah that's a solid move from @olivia670. It's like how people get used to a bad sound in their car because it's been there so long, they forget what quiet sounds like. You have to show them the before and after. Same with those phone filters that make skin look plastic, or that awful blue light on cheap TVs. Once you see the real thing next to it, you can't unsee the fake version.

Exactly! It's like the difference between glancing at a room and really looking at it. I once rushed a job and missed a whole section of floor that was off by a full inch. The building didn't whisper it, but I sure wasn't listening with my eyes. You have to walk it, measure twice in different spots, and let your brain catch up. That old timer knew you can't just run a tape and call it good.
