Are your players wandering around aimlessly just occasionally poking at things but otherwise doing nothing?Maybe following a plot isn't the point of the game.
Because I'm assuming that the players have goals. Maybe it's a goal they got because they bit a GM-provided hook. Maybe it's a goal they made for their group. Maybe it's a goal they wrote up in their character's background. In any of those cases, if they're ignoring those goals because they suddenly want to know why there's a really good waiter working at this one inn, they're not working on those goals, so it won't disrupt anything any further to say "I don't know."
