Yes there are probably a few bad hangers out there but if you believe that someone is having to adjust their hanger 10 times in a short period is normal, it is not. Having worked on some pretty bad bikes I haven't really run across these bad hangers, they weren't great but they certainly never needed adjustment 10 times or immediate replacement (unless otherwise damaged).
I've been the service manager on and off since 1990. Every bad hanger that ever came through my department got a look from me. So I don't know if you are just unaware of how many bikes a mechanic sees over many years, or if this is just the best you can do to discredit my (vast) experience.
No, flimsy hangers were not a common experience. But if you do anything enough, you will see them and have to deal with them. The ones I got the customer to replace were either better quality (aftermarket or factory), less fatigued or harder metal.
And this sort of thing is obvious. You see the bike come in once, straighten the hanger with almost no effort and then see it back a month later with the same minor bends that screw up indexing. You go into the box of hangers, compare with an alternative maker and it often solves the problem entirely. Especially when you set the alignment on the new one and it is clearly twice as stiff as the one it replaced.
I'm going to lightly agree with Spoonrobot - you come across as the typical bike shop owner/personality that the mechanics try to keep away from the tools.
