Both John and Sue joined the staff of a successful public relations firm in New York during the same year.
     (26) They had just completed their PR degrees at a nearby university and were thrilled to be hired by one of the finest PR firms in the city. John’s first assignment was to create a promotion campaign for a client who was putting a new game on the market. Initially Sue was assigned to work with a sportswear company on a marketing concept for its newest line of clothing. As time passed and work with their respective first clients became more and more difficult, John and Sue realized that they had been assigned two of the toughest clients in town. Although John completed his assignments quickly and successfully, he was furious when he learned that the boss had deliberately assigned him a difficult client. (27) In response he not only complained to his colleagues but also to the boss’s secretary. Sue, on the other hand, had a more difficult time satisfying her first client and she took several additional months to actually complete the assignment. However, she just laughed when she heard that the boss had made the assignment purposely. Over the next two years, John worked reluctantly with each assignment and problem that he encountered. Sue accepted each assignment cheerfully. And when problems arose, she responded with her characteristic "No problem, I can handle it." (28) Although Sue took longer to complete her projects than John and both were equally successful on the assignments they completed, Sue was given the first promotion when there came a vacancy. (29)
