Unfortunate because it's relatively easy now to mock-up the pretty part well enough to be mistaken for the real thing. Which people who don't have experience in this field then do, and get often get confused or upset even.

Example of this from another industry: working in manufacturing, a client wouldn't listen to our explanations about why their part wasn't ready to be molded in plastic. (lot's of design issues that would make it impossible to get out of the mold or lead to extreme cosmetic imperfections). To prove their point that their part designs were ready, they held up a 3d print of their part and said, "See? It's right here! You just have to do this!" This led to a half hour of answering questions before they started to understand that the two fabrication processes were very different and had different requirements.

I think the unfortunate part is really the time you have to sink into helping someone understand that's often unpaid, in my experience.
