My policy on social interaction rolls is that you can feel free to make them, but everyone else is just as free to ignore them :)<br/><br/>Skill checks can be fun ways to inform the story or help a player make a decision that they are otherwise ambivalent about, but they shouldn't override player agency. So a high persuasion check vs a PC would be a good reason for that player to have their character agree if they didn't much care otherwise, or a particularly low result might lead to some funny shenanigans, but ultimately they shouldn't have much if any weight. Now, vs NPC's, that may not apply of course. :)
