I'm now helping you help others with the chance to 'gift' coffee to a complete stranger. This is otherwise known as 'Suspended Coffee' and is a concept that originated in Naples, Italy. You can read more about it on the Australian Suspended Coffee website.
A caffè sospeso as it's known in Italy, is a prepaid 'suspended' coffee purchased anonymously, where two coffees were paid for but only received and consumed one. A poor person inquiring later whether there was a sospeso available would be served a coffee for free. "They are then provided with warmth and nourishment at no cost to themselves. Paying it forward, one coffee at a time. Humanity restored."
