The Langley, Virginia, Starbucks is one of the busiest in the world.

Located inside the CIA compound, it is also the most secretive, writes Emily Wax-Thibodeaux at The Washington Post.

Here are a few ways the so-called "Stealthy Starbucks" protects the identities of its CIA patrons.

1. Baristas don't write any names on the drinks.

"Giving any name at all was making people — you know, the undercover agents — feel very uncomfortable. It just didn't work for this location," an anonymous worker told Wax-Thibodeaux.

2. Workers are put through an intense background check process.

The address for the CIA Starbucks doesn't even show up on a GPS, one worker told the WashPo. Once workers get the job, they aren't allowed to reveal where they work.
