D&D 5E Bad Wrong Fun

[TwoSix]

Right on. But how about the devil's advocate version? Is it possible to questions a ruling with good grace in the moment? Or is it always disruptive?

I think it can be done correctly, but I've found most contentious rulings are based on discrepancies between how the DM thinks they described a situation and how a player is imagining the situation. So the best way to resolve the issue quickly is to look for where the break between the DM's imagination and the player's imagination occurs, and be willing to retcon if the player made a decision based on a misunderstanding.
