That brief period between when the driver gets in the car and when he unlocks the passenger door for a friend waiting to get into the car.
The passenger often tries to open the door a few times before it is actually unlocked. Sometimes the attempts to open the door and the actual unlocking of it coincide, and the attempt negates the unlocking.
Hey, keep your door lock anticipation under control! Quit trying to open the door until I unlock it!
