That's part of what makes me wonder if some of this stuff gets outsourced. Like, if they're just sending these things out to get printed, I don't expect some kind of sign-printing company to fact-check the things they're getting (in this case it's doable because it's public information, but if I was in the printing business I'd probably generally assume that the customer sent what they wanted printed). If this stuff is in-house, of course, that doesn't apply.
Also worth wondering to what extent the "authority" question (whether taking initiative is permissible) is tied to "not my job" considerations (please don't tell me there are union contracts/rules limiting who can "install" station signage) where someone may notice something amiss, but it's not their job to do so (regardless of whether it is officially permitted or forbidden to take initiative) so they simply...don't. (Not necessarily out of laziness, incompetence, or malice, mind you. They may, in this hypothetical, assume that the problem will be or is being addressed by the appropriate people.)
