A woman in front of me rummaged through her purse looking for a gift card to complete the remaining $14 of her grocery purchase, which was just over $30.
When she found her gift card and the cashier swiped it, the card was empty.
I slid $14 to the cashier.
She tried the gift card one more time, then acted as if the transaction had gone through successfully.
The woman got the groceries that she needed without finding out that I’d paid the remainder of her bill.
I felt happy, although she didn't thank me or even know it was me who paid that $14.
This day became a better day for her. And I knew that there was my contribution in it.
That was enough for me.
I could do something to make the world a better place. And that was already a grand reward for me.
