I found an interesting story online the other day which kind of made me mad. Did you realize that most buttons for closing the door in an elevator are just fake buttons? Years ago these buttons always worked but now the elevator door is on a timer and it doesn't help to push the button at all. Another button that most times is fake specially in New York City is a crosswalk button. You can push it all you like but it doesn't speed up the timer that controls the stop light. It's completely fake. Again years ago these worked but now they don't. They just want to give you the false sense that it does.
