The greeter patrols the front entrance to the General Atomics Galleria and welcomes the Sole Survivor. He's looking for the supervisor to re-open the galleria.[1]
↑The Greeter: "Welcome to the General Atomics Galleria! You must be our new supervisor." Sole Survivor: "I think you've mistaken me for someone else." The Greeter: "Oh, I'm sorry. After 428 false positives, I just felt so certain! If you happen to meet that laggard, let him know that he is 210 years late for his scheduled shift." (The Greeter's dialogue)
