Intern

An Intern is someone who is only working in a position to gain experience and training, rather than do it as a complete job.

With the PPC, interns are not just delegated to fetching coffee, but if they're able to fetch coffee, chocolate, and/or bleepka AND simultaneously help the Agents they've been assigned to, said intern is likely fast on the way to becoming a full Agent.

Not that it's very hard to become an Agent, given current hiring policies.
