Many medium and large sized airports operate at capacity or near enough capacity at night and/or in low visibility, without being able to see much or nothing at all.
With regards to shouting at the marshaller.. good luck with that, I thought they wore ear defenders against aircraft noise.. now it seems they can hear the controller shouting from the tower hundreds of meters away..
