E. I don't like staplers that don't have staple bullets and they don't inform you. You're getting ready to staple your papers, arrange until mei mei, corners make until aligned so nicely, then you take your stapler, and you oh so carefully kiap the thing. Only to feel it go down like, abnormally easy. Then you realise there's no bullets! Gah. All my xin ku ness for nothing. Then you leave your paper messed up and get some bullets. Then you come back and just give up on arranging the stack of papers since it already messed up its one chance of being arranged properly and just put it together haphazardly.
