I agree totally agree on both points. I also think though there is an opacity element, If you can’t see/will know if these service providers did a good “quality” job corners are habitually cut.
E.g. if I have a new button that’s been sewn on a jacket, or have my house painted, I can easily see if the right button was used, or if spots were missed while painting. However if I take my car in for an oil change, I don’t really know if the right grade of oil and an OEM filter was used, nor do I really care to recheck my accountants work on my taxes (as long is it roughly pencils to what I expected).
