What began as a single act of kindness ignited a chain of good cheer stretching 900 cars long.

A Dairy Queen restaurant in Brainerd, Minnesota was the scene of the pay-it-forward chain that lasted nearly three days.

The store manager Tina Jensen was excited on December 3 when a man said he'd like to pay for the car behind him, so she gave the heart-warming news to the people in that car, and then asked if they wanted to do the same.

"If you like I can pay it forward and you can pay for the order behind you and we can keep this going," Jensen recalled in an interview with KARE-TV. "She's like ‘really, why would he do that?'."

She agreed to make that Thursday a ‘lucky day' for the car behind her—and after that, the next car kept paying for whoever came next.

Jensen says, "One lady, she was so excited, she threw us a 20 dollar bill almost in tears. ‘Are you serious. This is really going on?' I said, yep, you are about 125 cars into it. She said, ‘For real, can you believe this?'"

The longest chain this drive-through ever experienced was 15 to 20 cars, but in 2020 with the holiday spirit in the air, everyone wanted to keep it going.

Tina posted about it on Facebook, and people started driving to the restaurant just so they could participate—all day Friday, and most of Saturday, they kept coming, and paying the tab for the person next in line.

The record ended up at over 900 cars, with $10,000 in sales from selfless customers who passed up the opportunity to take a free meal for themselves.
