Case: The Drop-In Visitor As the door closed behind her departing visitor, Jumanji Residential Supervisor Janet Mills glumly reflected that she had just lost an hour that she could ill afford to lose. She would either have to forego the schedule she was working on or be later for an upcoming meeting. The hour had been lost because of a visit from a pleasant but marginally aggressive sales representative trying to acquaint her with "the greatest little thing to come along". As was her practice, Janet consented to see the visitor although she resented the intrusion. This incident, occurring on a Friday, made Janet realize that she had lost time to four such drop-in visits this week alone. She did not like the idea of simply saying no or otherwise trying to avoid people who wanted to see her, but she was becoming more aware that her work was beginning to suffer because of such demands on her time.
