It's another day to celebrate free coffee.

Dunkin’ Donuts announced that today, the official first full day of spring, all 90 Dunkin’ Donuts restaurants in Baltimore will be part of the company’s first-ever nationwide Free Iced Coffee Day.

Customers at Dunkin’ Donuts can visit any participating restaurant today and receive a free 16-oz. cup of iced coffee.

The Starbucks Coffee Company ran a similar event last Thursday, distributing free 12-oz. cups off coffee.

“We see this [giveaways] because we were all sequestered during the winter and one way to get people thinking about going out is a great deal,” said Dennis Pitta, the Jay William Middendorf Distinguished Professor at the University of Baltimore. “As a wise man once told me, ‘There is no incentive as nice as a free hotdog.’ ”
