Your club decides to send four members to a conference on fundraising techniques for humanitarian projects being held in New York City. All the members pool their resources to cover the expenses for the four during their three days at the conference. As the club treasurer, you review the members’ receipts after they return in order to reimburse them for airfare, lodging, registration fees, and meals. You notice that two of the four were careless with their purchases, using taxis instead of public transportation, dining at expensive restaurants, and adding unnecessary room charges to their hotel bill.
What do you do?
