When it's a public service where exorbitant amounts of money are spent on it, and where it needs to serve the public and fails miserably. One thing that comes to mind is NYC transit, which replaced giant paper maps on the platforms with small non-touch LCD TVs that show a blurry, barely legible map -- that is, when they are not showing advertisements, promotions, or what amounts to government propaganda. In the above example, I know the cost associated with this change was huge, and that it utterly fails at its design goal, and that had anybody loaded the image on the TV just once before deciding to spend millions replacing all of perfect usable paper maps they would have seen how awful it looks -- and yet there it is, in front of me, at every platform.
Again with the above example, I fully realize it may not even be the fault of the "designer", per se, given the budget, politics, time constraints, whatever. Maybe it's because they need to cut labor costs by having a way to update service announcements without having humans replace paper postings on every platform. Whatever the reason, though, the shitty LCD tvs are in front of me every time I'm on a subway platform. I cannot escape it, I pay to see it, and I cannot change it.
Another reason for the personal offense is difficult for me to describe, but imagine an injustice were to happen to you, and you ask the person in charge: "You know this is wrong, but why can't you fix it?" they reply: "that's just the way things are", or "well, life isn't fair".
