Client Freaked Out Over My Custom Built-In Bookshelf Design - Total Rant

So I'm on this job installing a face-frame cabinet setup in their living room, and the client starts nitpicking every damn detail. I show up with my Festool Domino for the joinery, explain how it'll hold up better than pocket screws, and she acts like I'm trying to rob her blind. Spent two hours reassuring her that Benjamin Moore paint will match her trim perfect, but nah, she wants revisions that'd add a whole day. NGL, these difficult clients make me wanna stick to commercial gigs where they just sign off. Last week on r/Carpentry, someone posted about a similar headache with picky homeowners. Finally got her to approve, but man, what a waste of my afternoon. Anyone got tips for dealing with this BS?

Document every change request in writing, email it back to them with your time estimate added on.

Fuck these clients who think they're HGTV designers but pay like it's IKEA.

Been there, bro. Lost a whole weekend to one who changed her mind on the stain color mid-sand.

Haha, I once had a guy demand I 'test' his new shelf with his bowling ball collection.
