Dunkin’ (DNKN) is honoring healthcare professionals on the frontline of the coronavirus pandemic by giving them free coffee and a donut on May 6.

The “thank you” promotion is in honor of National Nurses Day to show appreciation and support for these healthcare workers’ “tireless efforts to keep us all healthy and safe.”

Healthcare workers will receive a free medium hot or iced coffee and a free donut when they visit a participating Dunkin’ restaurant nationwide.

No purchase is necessary to get in on the deal, and the offer runs while supplies last.

Most Dunkin’ restaurants are open nationwide with service limited to carryout, drive-thru ordering, and order ahead from the coffee chain’s mobile app. Delivery is also offered in a select number of locations.

“As a brand with a long heritage of serving those who serve, we appreciate and honor the heroic work and unwavering commitment nurses and healthcare professionals show every day,” Dave Hoffmann, CEO of Dunkin’ Brands, said in a statement.

“Their selfless sacrifices inspire all of us to come together to do everything we can to support our communities. We want people on the frontlines to know that we have their backs and they can count on Dunkin’ to help keep them running.”

Dunkin’ is also providing a $200,000 grant through the Dunkin’ Joy in Childhood Foundation to First Descents – an adventure-based healing program that provides critical support for nurses and healthcare workers that are experiencing trauma because of the COVID-19 pandemic.

Shares of Dunkin' stock were up 5.52% as of 2:25 p.m. EDT on Wednesday.
