If you're bad at filing their expense reports, don't join al Qaeda. The terrorist group is very meticulous in keeping track of its expenses. According to a report published by the Associated Press on Sunday, receipts found in a raid in Mali show detailed filings from jihadists. In fact, a purchase as small as $0.60 cake (rookie mistake, you always go for the more expensive cake for employee birthdays) is noted. Also found at the building were salary spreadsheets, letters from human resources, and workshop schedules. So even terrorism networks are just likeThe Office.
