I had a front mounted backwards by a bmw dealer tech once despite the fact I had drawn direction on both sides of the rim, in two places, w/ a Sharpie & the factory marks still being clear.
Svc mgr noticed me examining the wheel & asked what's up? I was trying to see if I was seeing correctly & wondering if I would simply turn the wheel around to re-install (dual-disc).
Mgr looked at the tire, shook his head, took it back to the shop for the remount. His philosophy was you just paid for a job to be done, not done improperly.
The aforementioned tech was not happy...fuck 'im.
Opinions are like internet connections- everybody has one.
