Reminds me of an escapade of my erstwhile boss, narrated by himself. When he was a graduate student, he often had to move between labs on the 5th and 2nd floors. He would enter the elevator, look at the floor number on the neon display, and press the corresponding button. The door would jerk open. Naturally!
After a few dozen "mishaps" like this, he abandoned the elevator altogether and completed the rest of his PhD programme walking up and down the stais whenever needed.
