Doesn't everyone know that pressing the button at a pedestrian crossing does absolutely nothing except turn the "Don't Cross" light on? I tell you this from the experience gained from years of angrily stabbing at the damned things!

Are you not familiar with the impatience switch? The more you press the button, the longer it takes the lights to change. I believe the same principle applies to the 'close doors' button in elevators.

Rapport was established superficially.
