Paying a forward forward

At a coffee shop I stepped up to the counter to order my standard small Cappuccino . The Barista looked uncomfortable as she informed me that someone had paid it forward and my Cappuccino was no cost to me. Surprised and clearly uncomfortable,  I suggested that she give it to the next person in line. She did and that person was delighted.

Why did I not take the drink? Did I not want to owe a person I never met? Did someone need it more than me? Would I appear greedy? Whatever the reason, I passed on a kindness. The world moved on carelessly.

I believe in the kindness of others, but it can be awkward to be the recipient.
