I suppose it depends. Maybe something isn’t worth doing in house. Like for instance if the parts show up unfinished or damaged you don’t pay someone to straighten bent rails, chamfer bolt holes and de-burr surfaces. Maybe you pay the vendor a bit more, find a new vendor, or hire a middleman to bring the parts in ready to ship.

Paying your support staff well is virtue signaling to be sure but as someone who’s always had a soft spot for top shelf QA and support folk, that’s not a bad thing.
