You may have seen a viral video going around recently filmed from inside a New York deli & grocery store, also known as a bodega. The person behind the camera asks an unsuspecting customer a simple math question, and if they get it right, they have 5 seconds to pick up whatever they want from the store for free. What started out as a series of fun social media videos has turned into a national story with a simple but heartwarming message: kindness can go a long way.
