Oh, I know the perfect example of that. Two groups of three meet, everybody greets everybody else, in an individual textbox. That's 9 lines of dialogue "A: Hello B", "B: Hello C", and so forth. Even though there are - I think - some individual renders for that, that's not good storytelling, though the dev insists it be "realistic". Which I doubt, but even if, there is a reason why hardly anybody goes to the toilet in a movie: it is realistic, but - as per your criteria - it does not build character ("Oh, he is one of the guys who indeed does poop - that completely changes my perception of him" is a sentence heard only occasionally), nor the scene, nor the story.
