What does "runners" in a correctional facility usually do?

In the context of a correctional facility, "runners" refer specifically to individuals, often inmates, who transport items or messages within the facility. The role of a runner can involve moving between different areas of the prison, delivering various items that may not be officially permitted, or conveying information between inmates and outside contacts.

The option that states runners expose themselves to officers to request small items accurately reflects this function. It indicates a behavior where inmates might signal to or directly approach officers to obtain contraband or even ask for minor items, underlining the informal and sometimes illicit channels that can exist within the correctional environment.

While other roles mentioned, such as managing inmate schedules, overseeing contraband control, or preparing food, are important functions within a correctional facility, they do not encapsulate the specific responsibilities associated with "runners." The unique nature of a runner's activity aligns closely with the behaviors described in the chosen answer.
