Elevator indicators

The indicator of our elevator goes off just before the lift actually opens. Considering the seeming reluctance with which the doors open, there is ages between the indicator light switching off and the doors opening. So, if you are waiting on a floor and someone enters the scene just after the indicator lights go off, you would just look to them like an ignoramus who cant press a button, or better yet, a person who can summon lifts without even pressing a button!
