...borrow it until it was returned for more staples...
Classic.  
Reminds me of a story my FIL, and electrician, once told.  He was on a job site in the city and gave his helper some money to go buy them each a coffee.  His helper returned with one coffee and proceeded to start drinking it.  When asked why he didn't have two coffees, he responded: "On the way up, I dropped yours."
