When I worked at the Pentagon I ran into two French university students outside the South Parking entrance. They wanted to take the tour but were horribly lost and couldn't get help as their English was bad. They'd missed the last tour of the day at that point and were due to leave the next day, so I showed the young ladies around the public areas. They thought that the Ground Zero Hot Dog Stand and Grill (named pre-9/11, relax) was disturbing. I got thanks and some chocolates from France when they returned home.
