A rock band was about to begin a grueling four-month world tour. The band’s manager telephoned a massage therapist and said that he would like to reward the band for all their hard work on the tour by booking massages for all of the band members immediately after the last show in the tour. The therapist agreed to perform the massages at a deeply discounted rate because she secretly was a devoted fan of the band and excited to have the opportunity to meet the band members. Just before the first scheduled performance, the band’s singer developed a rare throat infection, and as a result, the band had to cancel the tour at great expense. The manager notified the massage therapist that her services would not be needed. The therapist objected and demanded that the manager arrange for her to perform the massages for the band at a different time.
