6 chains including Starbucks and Krispy Kreme are offering free food and drinks for healthcare workers and other first responders

Krispy Kreme announced on March 28 that it would give healthcare workers free doughnuts at drive-thrus. The chain said it would give any healthcare worker free dozens of its original glazed doughnuts, provided they show their employee badge.

The personal-pizza chain announced on March 14 that starting March 16, hospital workers could order free pizzas in-store or via text for delivery.

Hospital workers can show their ID at an &pizza location to get their free pizza, or they can text "#HERO" to 200-03 for a delivery code.

Nando's Peri-Peri is providing catered meals to hospitals, and the chicken chain also said it would give hospital workers free meals if they visited a Nando's restaurant in uniform and presented their hospital ID. Free meals will be available at all Nando's locations in North America through May 3.

Nando's is also offering 50 free meals a day to restaurant workers who have recently been laid off.
