Coffee Stencils: If you've been searching for the best way to demand your boyfriend repay you from last Saturday's bar crawl, but you hate confrontation, here's how you can send him the message nicely. Just put one of these custom made coffee stencils in his coffee, sprinkle in some cinnamon or something, and watch as he is shocked by the appearance of a personalized message in a place where there usually isn't one. Either he'll have the money to you by the end of business day, or you should go ahead and invest in the stencil pictured.
