Gran Caffè Gambrinus shared by @searchingforstanley says: "Back in Naples, a police captain teaches Stanley about the Neapolitan tradition of Caffè Sospeso: he buys two coffees and one extra, so when a person in need shows up, the coffee seller gives them a free drink that their fellow citizen has paid for earlier. Gran Caffe Gambrinus, the oldest and perhaps grandest cafe in Naples, is one of the cafes in the city that practices this tradition." on Postcard
