GD&T: When did companies start thinking that Total Runout could lack a datum? (lemmy.world)

I've been dealing with this for months. I've received yet another drawing from a company calling "Diameters on a common axis/center to be 0.XX" TIR U.O.I. "

Total Runout requires a Datum. Your "common axis" is not a datum and can not referenced. It's driving me mad. Like, where did everyone get this notion that it's acceptable? It'd be one thing if it was just one or two drawings, but I'm into the dozens at this point. It's getting to the point that I'm starting to question if I'm either the one in the wrong or everyone has some sort of mass psychosis.

Am I in the wrong here?
