Elevator button mischief has been happening as long as there have been elevators and kids (and that guy from accounting who thinks it’s funny to slow you down).
It seems like this happens only when you’re running late: you step into an elevator and see that someone has pushed every button. There’s no need to stop at each floor, though. Here’s a hack to remember: press each button twice to cancel the “call.”
And you’ll be on your way.
