Well, my experience is different than yours.
First, why should you assume that your experience applies to Mim and that she does not spend the time to ensure that all is done well for every ukulele she sells (I understand she does it at festivals that she attends). You conclude others are doing poorly or the minimum because of the one experience you have. And yet numerous others here have cited their positive experience with her work. So perhaps if you had purchased from her, you would think setups are great, but you might wrongfully conclude that everyone that perform setups do an equally good job.
I have purchased a few ukuleles from TUS. The free setup had level frets without any sharp corners (like I have seen in other shops with K ukuleles. One included a free change of strings to Uke Logic and the action set to a specified height at the 12th fret (and not the 3 mm often seen in ones preceding setups). There was some dye irregularity that they observed which led to a discount (not by my request). And I personally observed an employee working on a setup at their Kakaako store for a rush pickup that day.
They have a video on their website showing the setup process, which they are rightfully proud of. So to answer your question: I do not question whether they follow this process on all the ukuleles that they setup.
