LINDENHURST, Long Island (WABC) -- A coffee shop in Suffolk County is spreading kindness using Post-it Notes. In October, the owner of Muni's Coffee Joint in Lindenhurst, Alice Bopp, allowed customers to buy a cup of coffee for other customers and leave the order on a Post-it Note on a board in the shop. Bopp said a customer saw the idea on social media and presented it to her, and that it's meant to show people that strangers can care for each other. "To give a little cheerful, to give a little positive word in such a down moment," Bopp said. "We're going through this whole year."
