What better way to celebrate National Doughnut Day than with a free treat?

Shops across the country are marking the occasion with free pastries Friday.

Some, such as Dunkin' Donuts and Cumberland Farms, require purchase of a beverage to get the freebie.

National Doughnut Day was established in 1938 by the Chicago Salvation Army to honor women who served doughnuts to soldiers during World War I. The holiday is traditionally celebrated on the first Friday of June.
