A Gracious act of kindness

Today I was in a convenience store, Cumberland Farms, getting myself an iced coffee and my sister as well. I get to the cashier and he said, Is that all? I said, Yes. He replied, You're all set.
And I looked at him not quite understanding, and he replied again, You're all set! I said oh Thanks so much!
He said no problem! It was such a nice gesture to get our coffees for free..it made my day 🙂There's some good people out there after all!
