Shia LaBeouf -- Someone's Getting Fired

Shia LaBeouf flew thousands of miles Monday -- from Germany to L.A. -- but he had to go an extra mile when he landed ... meandering through LAX looking for his limo driver who was MIA.

It's actually painful to watch. An independent paparazzo spots Shia as the actor begins his very long walk. Other photogs catch up, as Shia is silent, looking in vain for his driver.

The worst part -- he walks by a slew of drivers holding signs -- none for him.

Finally, a panicked driver appears and takes Shia on an endless walk to his car.
