People will still queue around the stainless steel railings inside. Do you see the glass doors where the exit sign is? That's where the glass doors are. When the bus arrives and is ready board passengers, the glass doors will open and passengers will slowly board the bus.
Passengers can "hide" indoors first, before the bus arrives :P Does your country or city have an indoor terminal or interchange?
There was another post of a outdoor bus interchange earlier last month.
