Tough economic times and growing poverty in much of Europe are reviving a humble tradition that began some one hundred years ago in the Italian city of Naples. It's called caff sospeso - suspended coffee": A customer pays in advance for a person who cannot afford a cup of coffee. The barista would keep a log, and when someone popped his head in the doorway of the cafe and asked, "Is there anything suspended?" the barista would nod and serve him a cup of coffee ... for free. It's an elegant way to show generosity: an act of charity in which donors and recipients never meet each other, the donor doesn't show off and the recipient doesn't have to show gratitude. It's fitting that the tradition started in Naples, a city that prides itself on having the best coffee in Italy. The caff sospeso tradition waned as Italy entered the boom years of postwar reconstruction and La Dolce Vita. For decades, the custom was confined mainly to the Christmas season. Now, it's made a comeback. Two years ago, with the eurozone crisis already raging, unemployment rising and small businesses closing on a daily basis, more and more Italians could no longer afford the national beverage - an espresso or a cappuccino. Then someone remembered the old Neapolitan custom. So several nongovernmental organizations got together and - with the support of Naples Mayor Luigi de Magistris - Dec.10 was formally declared "Suspended Coffee Day." The practice is now spreading to other crisis-ravaged parts of Europe.
