And would they be the mechanics like the ones that post here all the time telling you to not whack your hedset in or out with screwdriver and hammer? Even the less competent shops I have visited have the proper tools for such work. They may not know how to use them. But it beats a guy with a claw hammer and a twobyfour.

In my years I have never seen a screwed head tube by a pro. Seens lots of amatuers tear up stuff, even things you would not think they could mess up.
