Do not underestimate the power of social media. This woman certainly doesn't. Watch Taylor Chapman record her own rant as she goes back to a Dunkin Donuts where they (gulp) failed to give her a receipt the previous night after placing a large order. Now she's back with a vengeance demanding her free order per the store's notice that you get a free meal if they fail to give you a receipt. Watch her document the entire thing on video.
