I somehow get giddy when I come across an elevator whose “Close Door” buttons actually work. I’m not sure why they are disabled in most elevators. However, once I come across one where the buttons work, I make a point of pushing the “Close Door” button.
I’m not entirely sure of the point of the “Open Door” button though. I don’t think I want the door to open as I’m whizzing up 20 stories in 30 seconds.
