President Obama was so heavily guarded by an elite Secret Service team as he left a Virginia burger joint ... even his doggie bag got protection.
Check out our video of POTUS and Education Secretary Arne Duncan and others as they surprised diners Tuesday afternoon at FireFlies in Alexandria, VA.
The Prez ordered the American Way Burger with cheese, lettuce, tomato and mustard ... and fries and a side salad. Total bill -- $73 ... Obama left a $50 tip.
As for running with the doggie bag ... it's a job any Secret Service agent would relish.
