Most of the shop mechanics are not even trained and many know less than you do about your bicycle.
I don't need to use shops often but recently had a new set of wheels tensioned. Despite the shop having a racing heritage and sponsoring a local team, I did not just clamp them on my bike and race them or bomb down a huge descent without examining them and taking a few easy test rides first. That's just how I am. There is too much at stake to not check their work.
Ah, I see the distinction you're making, however, there is no such oversight for a lot of the work we 'trust' everyday, and in the same way we don't expect anyone to double check their mechanics' work on their car, the same is true for the bike shop. None of which is to say you shouldn't do it, nor that it's not best practice to do so, even, only that your perspective is unique, and that in all facets of business and commerce, someone paying for a service is fully entitled to the expectation it be done right.
