From Napoli to London and beyond, local cafes are providing their customers with a simple way to pay-it-forward. It's called "suspended coffee." When you purchase coffee for yourself, you can buy a second cup, which goes on account to be claimed by whoever might want one. It not only allows cafe patrons to express their generosity, but also builds a sense of inclusiveness and community by creating a shared experience between those who can afford the luxury of a good cup of Joe and those who cannot.
