A single random act of kindness stirred up a blizzard of good deeds when a customer paid for the car behind him at a Dairy Queen drive-thru in Minnesota.

It started on a chilly day in the city of Brainerd, Minnesota about 100 miles north of Minneapolis. Feeling generous, one man wanted to warm the heart of the driver behind him by paying for their cold treat. The result was a chain of kindness that spanned over the course of two and a half days.

Tina Jensen, store manager of the Dairy Queen, told CNN this was not the first time a customer had paid it forward at the location. However, she says such chains typically lasts for a dozen or so cars before fizzling out. In this case, Jensen says more than 900 cars participated, generating approximately $10,000 in sales.

As news of the chain began to spread, customers continued to flock to the store for a chance to participate. Jensen kept the public updated through the store’s Facebook page, finding the community was eager to come together to continue spreading goodwill.

“There’s all different types of ways to help people,” Jensen told CNN. “I think this touched a lot of people that we didn’t even know it touched, deeper than we know. And you don’t know what’s going on in a person’s life.”

When the Dairy Queen location closed that first night, a customer left $10 to keep the chain going the following morning, and once again on the next day.

“During times like these it kinda restores your faith in humanity a little,” customer Heidi Bruse told CNN. “The way the world is now you see a lot of anger, tension, and selfish behavior. What we witnessed was pure kindness and it was a breath of fresh air really.”

Like many restaurants across the country, Jensen says the location has faced challenges during the pandemic, struggling to thrive due to protocols put in place in the interest of public safety.

“The lobby shutting down, being only open for take out, being able to open for half your capacity, different things like that,” she said.

While Jensen has tried to keep the workplace morale high while also maintaining customers’ safety, she says this gesture was exactly what her employees needed to lift their spirits. Jensen says her staff was touched each time they could tell the next customer their order had been taken care of, and became more positive with each subsequent transaction.

“No matter what’s going on, take care of each other, be positive, be happy and don’t focus on the negative,” she said. “We’ll get through it.”
