I would argue that was by design. In life, things don’t happen in such a perfect order. I think he was trying to make the characters more fleshed out, especially as they had so little depth or development in The Force Awakens.
Well, movies aren’t real life. It’s like complaining about how nobody sneezes in Jurassic Park, or how nobody goes to the bathroom in Avengers. That sort of awkward stuff is typically removed in movies to increase tension. As a third-person observer, stupid jokes and awkward humor can kill tension flat.
The Diplodocus sneezes in Jurassic Park and iron man pees in his suit 😉
Goddammit MR, you ruined my point! 😉
Although technically, those were just one off gag sequences, and didn’t interfere with the tension of the movie. I was just contrasting that to TLJ’s nonstop use of bathos.
