A note written anonymously has garnered attention after a man identified as "Andy" posted it to Reddit last week, describing an act of generosity that took place in the Tampa International Airport.

Andy had been traveling and was asked to pay the mandatory baggage fee. After handing the employee his credit card, Andy was told his card had been declined. Embarrassed and upset, Andy stepped away from the counter to call his bank and double-check his balance.

Upon returning to check out, the man found a note left for him on the back of a receipt. The note read:

"Hey, I heard them say your card was declined. I know how it feels. Your bag fee's on me. Just pay it forward the next time you get a chance. Have a safe flight. :)"

Andy was overwhelmed by the kind act and decided to post the photo to thank the anonymous giver.

"If you're reading this, thanks for making my day," Andy posted online.

But according to Andy, the financial help wasn't even the best part of the surprise note.

"Seriously, reading their note gave me goosebumps and gave me faith that there are still good people out there," Andy told Yahoo Shine.

Many commenters have asked Andy what he will do to pay it forward to someone else. Andy said he hoped to come up with something spontaneously, just as it happened to him.

Many other users on the popular site left comments sharing their own "good Samaritan" moments.

"I was walking down a busy avenue in my city one day and saw a meter maid beginning to write a ticket for a car parked by the road. Obviously the meter was expired. As I witnessed this and approached to pass this event, I reached into my pocket and found some change, I passed between the meter and the maid, casually dropping a quarter into the machine, giving the person a few more minutes of time," one user commented.

"The meter maid was dumbfounded and my group and I paused down the street a bit to see her on her radio requesting advice on what to do. She ended up moving along and not writing the ticket."

Another user described an experience he had when he overheard a young mother describing a problem with her car to a mechanic.

"I heard her ask the counter guy if he could see why her lights were dim on the car. He went and tested and found the battery was dead, but the alternator was charging. I overheard her talking with the guy about batteries, and when she saw the prices, she kept asking if he had anything cheaper/smaller that would work," the user wrote.

"As she was leaving without a battery, I walked over to the guy and asked which one she needed for her car. He pointed. I handed him my card and rang it up. I grabbed the battery and borrowed some tools and walked out the front door just as she had finished buckling the kids in. I asked her to pop her hood, and she at first looked at me like 'What?' and then saw what I had with me.

"She asked me why, and I just said, 'Because someone did something nice for me once.'"

A few weeks ago the Deseret News reported on a similar act of generosity. In Massachusetts, a doughnut store celebrated a 55-person pay-it-forward chain after one customer first decided to pay for the customer behind her in the drive-through.
