The personnel collect data. All sorts of data. Let the players find storerooms filled with millions of volumes of such useful information, and they'll be begging to return to the Cafeteria. Just put some nasty-looking Violet guards where you don't want the Troubleshooters to go. The diligent clones here have work to do, and no time to mollycoddle nosy players.
Clerks bustle to and fro, operators enter data, and the PCs are in the way.
Have an angry Violet manager yell at everyone to get out of his department. Maybe send in a few security guards to enforce the law. You can't go home again. There are tall clones and short clones, males and females, Indigos and Violets. Darth-V might be in this crowd, but you can't tell for sure.
