The same at pedestrian crossings. You're standing there next to a quite clearly lit button, yet someone will come up and press it again as if it's going to make the lights change more quickly.
Same with lifts.........
...and whilst I'm on that particular topic, people who stick their hand through a door that's closing, or put their hand through the door to hold the lift whilst they finish their conversation with someone outside the lift.
...and people who impatiently repeatedly press their chosen floor button
...and people who try to get into the lift when people are trying to get out
Yes, the lifts in my office are a right pain in the arse, made worse by bellcheeses.
