Both dungeons will take you 30 minutes or longer. Therefore, it'd be worth taking the chance more often than not, especially when you may not be the one getting the penalty if someone else leaves first. Another problem is a system which detects if someone is new could easily be exploited by simply kicking that person.

Either way, you're given such a massive amount of EXP to compensate your time. Asking for ways to expedite defeats the intended purpose. In any hypothetical where you could skip cut scenes again would likely have the rewards sliced in half if not more.
