Anonymously buy a cup for someone that could use the help

"A caffè Sospeso (Italian for '"suspended coffee"') or pending coffee is a cup of coffee paid for in advance as an anonymous act of charity. The tradition began in the working-class cafés of Naples, where someone who had experienced good luck would order a sospeso, paying the price of two coffees but receiving and consuming only one. A poor person enquiring later whether there was a sospeso available would then be served a coffee for free.
