M-Cn: l like to finish calculating the company's expense reports for the month. Have you finished reviewing the travel reimbursement forms from al the departments? W-Br: almost done, but I have a question about a hotel receipt from one of our employees. W-Br: Well, our policy is for employees to stay at a hotel that's on our list of approved accommodations. This one isn't on the list. M-Cn: Who submitted the receipt? W-Br: Moritz Ziegler, one of our sales representatives. M-Cn: Hmm. He’s a new employee and may have forgotten the policy. As a supervisor, I can approve the expense this one time.
