The capacitor could be left with a high voltage across it when unplugged, but it would probably have a low capacitance, so the charge that flowed through your colleague''s hand would be small, though nonetheless unpleasant.
capacitor
As for the capacitor, touching one side of a charged object is rarely fatal. You have to touch both sides to complete the circuit and discharge the current. If you only touch one side, it becomes an electrostatics problem, where electrons shift into your body to balance the charges out. As it would happen, we deal with charges like this constantly.
