A customer walked into his pizza shop and changed Philadelphia with $1 and a Post-it note.
They had me at "fresh, hot pizza."
Rosa's Fresh Pizza offers a taste of New York-style pizza to the people of Philadelphia.
But that's not all they serve. Rosa's and their customers have teamed up to feed the city a daily taste of hope and kindness.
Philadelphia is the poorest large city in the country.
Heavy, right? Well, this particular story takes a happy turn.
At Rosa's, customers can "pay it forward" by pre-purchasing slices for people in need.
Owner Mason Wartman, who left his Wall Street desk job to open the shop, says pay-it-forward pizza started with one customer, one dollar, and one Post-it note.
The customer was inspired by an Italian coffee house practice called caffè sospeso (suspended coffee), by which customers can pre-purchase cups of coffee for less fortunate customers.
Wartman wrote the purchase on a Post-it and slapped it on the wall behind the register to be redeemed by the next homeless patron to enter the store.
As word spread, more and more customers participated.
And Rosa's wall blossomed with colorful notes signifying acts of kindness and a guaranteed slice for everyone who walked in, regardless of their ability to pay.
Since that first pay-it-forward slice, Rosa's has provided nearly 10,000 pizza slices to needy Philadelphians.
Pre-purchased slices now represent a whopping 10% of Rosa's business. And it's having a remarkable impact on the community, showing not only that acts of kindness can be contagious, but also how a small gesture of support can have a ripple effect of positivity.
In the video, Wartman tells the story of a homeless regular who disappeared for a while only to return having found a new job and wanting to pay it forward as others had done for him.
And in an interview with the Pittsburgh Post-Gazette, Wartman notes that some have even said the program has helped to keep them out of trouble with the law:
"[Wartman] said people who receive the slices have told him the generosity helps them avoid committing petty crime to get money for food. 'I knew it saved people money,' Mr. Wartman said. 'I hadn't considered that it stopped people from committing crime.'"
If one small business acting as a hub of kindness can have this kind of effect, can you imagine the possibilities of entire communities of consumers and businesses doing the same thing?
