At a few stores, the credit card machines allow you to get away with not signing your receipt if your purchase is below a certain amount ($25 I think).  This is the best thing in the history of the world.  I'm not sure why we sign receipts anyway.  Is my scribbled signature a confirmation that I'm the person who's using my credit card?  Couldn't anyone sign a sloppy name and use a stolen credit card?  And who came up with this $25 amount?  Is $25 too little for fraud catchers to worry about?  Either way, I'm a huge fan of this system because I can use my credit card without signing some stupid little piece of paper.  Two of the places that use this system are Quizno's and Wawa, which are arguably two of the best stores on the planet.  Now if I can only get Dunkin Donuts and Walmart to adopt this system, my life will be officially complete.
