I'm sure you all have experienced those nice kids that will get on an elevator and press all the buttons.
My wife found the perfect get-back for that.
We boarded the elevator on deck 3 going to 11. A couple of kids get on at deck 4 One of them presses all the even numbered buttons (2, 6, 8 and 10). His friend asked why he did that when they were going to deck 2. He stated it was fun. We finally got to 11. On the way out of the elevator, my wife pressed all the buttons and told them to have a nice ride down. (Evil, perhaps, but well deserved).
