You are traveling to a business meeting and because you are not familiar with the area, you take a taxi from the hotel to the meeting site. The site is closer to the hotel than you realized and the cab fare is only $10, even after adding a generous tip for the driver. Your company's policy states that all actual expenses must be reported, but expenses under $25 need not be itemized with receipts. You report $20 for the cab fare and throw the receipt away.
