Each shop to their own. I tend to not try to destroy things just because the customer can't see them when done....
And it's a giant PITA to clamp on the wheel outer edge, you have to break the bead first and then can't air up with it clamped, it is no wonder most techs wouldn't do that very regularly.
But a center post machine fixes both problems

So you accuse of destroying things to which nothing could further from the truth but then conplain of the pita to axtually do it the right way bu clamping on the outside?
I live in the rust belt and trust me when I tell you steel wheels get pretty bad all on their own hiding underneath wheel covers.
At the very least 75 percent of the wheels we get have previously been clamped by someone else on the inside with the subtle teeth marks on the inner part. Virtually all steel wheels and most definitely aluminum wheels are damn near 75 percent. Especially on steel wheels. Clamping in that same spot is negligible and I don't know about you but we've never once got a complaint about teeth marks from a previous garage or us especially on wheels you can't see underneath plastic wheel covers.
We don't care nor complain about the extra step involved in clamping on the outside to do the job right.
What we do hear complaints about repeatedly is other garages (even new car stores) putting clamp on wheel weights around the rim edge of their nice looking aluminum wheels. Something we never ever do. Ever!
I'm sure you know exactly what I speak of with that. Places trying to save a buck reusing clamp on weights no matter the wheel finish. That's completely unacceptable
