DELRAN, N.J. — One server’s act of kindness paid off in a big way.

Two firefighters stopped into a the Route 130 Diner in New Jersey for breakfast Friday morning after spending 12 hours battling the inferno at a warehouse in New Brunswick. When they were finished eating, their waitress presented them with a heartwarming note instead of their check.

“Your breakfast is on me today,” the woman, who signed the note as “Liz”, wrote.

“Thank you for everything that you do; for serving others & for running into the places everyone else runs away from.”

One of the firefighters, Tim Young, posted a picture of the note and the diner’s sign to Facebook, urging his friends to leave a big tip for the selfless waitress.

Young also found a GoFundMe campaign for Liz’s father, who was in need of a wheelchair accessible van.

“Turns out, the young lady who gave us a free meal is really the one that could use the help,” he wrote.

Young’s post went viral, and more than 185 people who heard about Liz Woodward’s good deed donated to the cause, surpassing the $17,000 goal to more than $53,000 as of Saturday morning.

Woodward posted a lengthy letter of appreciation to her own Facebook, writing “We are so grateful for your love and generosity.” She also gave an update on the family’s search for the perfect wheelchair accessible van and posted a video of her father saying “thank you.”

Her little act of kindness paid off in a big way and proves the theory that one act of of kindness eventually leads to another.
