Reminder!
Don’t take the vault decoupling lever from the vault maintenance area. None of you need it! The braking hatches on the vault are locked for a reason. Michaels has a master key, but I better not hear that one of you louts asked her for it. That key also unlocks the main vault—which none of you have security clearance for. If it happens again, I’m docking coin from everyone.
