Julie is attending a statewide trade show, displaying the signs and equipment that Round-The-Bend use and showing video footage of their traffic management in action. Michael comes up and chats with her about the business and the kinds of job that they take on. He explains that he's looking for a traffic management team to help with an unusual project, working in conditions of low visibility on a steep mountain. "Hmm, that does sound tricky," says Julie. "But I know how we can do it. We just need to get some special electronic equipment to go with our traffic lights. It can keep the whole system connected and then we can pre-empt the problem of the limited visibility. We don't normally need such a system, but for a job like yours I think it would be a good solution." "Great! I have been trying to find a business that will take this on. It sounds like you will be able to handle it well," says Michael. "Yes, we can handle it. But I'll need you to set out all the details in writing - you can send me everything via email or fill out the form on our website. Here," explains Julie, as she hands over a business card. "No problem, I'll do that by tomorrow," responds Michael, as he takes the card and puts it in his pocket. But three days later, Julie still hasn't heard from Michael. She's wondering whether to go ahead and order the special equipment and electronics needed to take on this unusual job. She looks up the details of Michael's business, and calls him. She asks if he's still interested, and reminds him that there are extra details, like dates, location, and hours, that he needs to indicate on the form. "Yes, we're definitely still interested! I've just been too busy to fill out the online form this week. But we're on for the project. So, do what you need to do, and you'll have all the details from me soon," says Michael. Julie goes ahead and orders the special equipment, which costs $3,000. A week later, the online form still hasn't been completed. Julie calls Michael but he doesn't answer. The next day she receives a voicemail from him saying that he's no longer going ahead with the project.
