In the working-class cafés of Naples, someone who had a lucky day would order a caffè sospeso: pay for two coffees, drink one. Later, a person who could not afford a coffee would ask if one was waiting, and get it for free. One account calls the tradition more than a century old. A reporter in 2008 found bars where nobody had seen it in fifteen years.
I like it because it is charity without a stage. No name on a wall, no ceremony, no thanks required. The giver never meets the receiver. Much corporate social impact is the opposite: loud, branded and timed with a press release. A business can do good the Neapolitan way. Build the extra cup into the price, and do it quietly, every day. That is what I want a social enterprise to be.
