You work for Red Co. You and a colleague, Pat Brown, are asked by your manager to attend a weeklong conference in Los Angeles. At least 25 other employees from Red Co. are attending, as well as many customers and competitors from other institutions. At the conference, you attend every session and see many of the Red Co. people, but you never run into Pat. Although you've left several phone messages for her, her schedule doesn't appear to allow room for a meeting. However, when you get back to the office, the department secretary, who is coordinating expense reports, mentions to you that your dinner in L. A. must have been quite the affair. When you ask, "What dinner?" she describes a dinner with 20 customers and Red Co. employees that Pat paid for at a posh L. A. restaurant. When you explain that you didn't attend, she shows you the expense report with your name listed as one of the attendees. What will you do?
