The scene where Bruce Willis enters the Nakatomi building, he approaches the desk clerk and says, "Holly McLean?" The clerk tells him to punch it up on the interactive touch screen, which Bruce does, and when a map pops up, Bruce says, "Thirtieth floor?" To which the desk clerk responds something like "Christmas party. They're the only ones left in the building." Okay, so if they're the *only ones* left in the building, why didn't the clerk just say "Thirtieth floor" in the first place?
