I’ve been at this almost 40 years and it comes up constantly. Typically when bad things happen to PCs. “I want to pick the lock” very quickly morphs into “I never said I actually pick the lock” once the referee assumes intentions equal actions and applies any consequences to the character based on the assumed action. Some players like to play word games as a shield against bad stuff happening to their PC. So either the player explicitly declares an action or their character doesn’t perform any actions. Having a clear idea of what they intended is really helpful to make sure everyone’s on the same page.
That sounds like bad communication, partially fueled by ingenuous statements, bordering on intentional deception. The distinction between actions and intentions is clearly not the root of these problems.
