With Nix having left, and short on staff due to the dinnertime rush, Summers needed someone to take Nix's place in the office. She spotted Thomas Simms, the restaurant's maintenance man, who had stopped in at the restaurant for dessert. She told Simms to go into the office and watch Ogborn. Simms, however, refused to go along with the caller's demands. At this point, Summers became suspicious and decided to call a higher-level manager (whom the caller earlier had claimed to have been speaking to on another phone line).
