Nadeem was looking for summer employment. He decided to purchase window washing equipment and approach various merchants on a busy shopping street in the middle of town to offer his services. One particular store, a bakery, had several large windows that were streaked with dirt, so Nadeem approached the owner, Lena. Lena was in the process of serving a customer and had several more waiting in line. Nadeem caught her between customers and offered to wash the bakery windows once a week. Lena, who was understaffed and very busy, replied, "Fine, just bill me at the end of the month," and returned to her customers. Nadeem cleaned the shop windows for the month of June and delivered an invoice at the end of the month.
