Wait till I unlock the car door before you pull the handle

Have you ever noticed that the passenger of your car always manages to pull the door handle just as you're about to unlock the door?   


Guess what happens?  The door doesn't unlock, and they don't get in the car.


So, you try unlocking it again - and at the very same time, the passenger again pulls on the handle.  The door still doesn't unlock.  


Then the driver has to say "wait a sec - don't touch anything"... unlock the door... and then the passenger can enter.

If you're going to get into my car, wait until I unlock the door before pulling on the handle!
