Nonetheless, many businesses require much more of their employees. Either because they don't know better or because they have odd contractual obligations when they pass disbursements on to a client. There are still business which require the "original" boarding pass along with a receipt, despite the fact that there likely has not been an "original" boarding pass for a good long while and the fact that a boarding pass exists proves not very much.
In addition, multinational companies often require the most stringent documentation for a group of countries in which they operate. Simply for ease of administration.
