Heartwarming Story of How Firefighters Repaid a Waitress' Act of Kindness One kind act led to another.

 -- One act of kindness led to another in New Jersey when a waitress' decision to pay for some firefighters' breakfast prompted strangers to help her.

Two firefighters stopped in a diner after an overnight shift containing a warehouse fire earlier this week and had breakfast at the Route 130 Diner in Delran, according to ABC News affiliate WPVI.

A waitress, Liz Woodward, overheard the firefighters, Tim Young and and Paul Higgins, talking about the fire. That's when she decided to pay them back for their efforts, according to WPVI.

She wrote a note on the back of the check -- complete with drawn fireman's helmet and ax.

Young then shared a photo of the check, along with a call for his friends to visit the diner, and to "tip big" if they ever had Woodward as a waitress.
