“Don't honk your horn at old people.”

I was in the McDonald’s drive-through this morning and the young lady behind me honk her horn because I was taking too long to place my order.
“Take the high road,” I thought to myself.
So, when I got to the first window, I paid for her order along with my own.

The cashier must have told her what I'd done, because as we moved up
she leaned out her window and waved to me and mouthed "Thank you."
Obviously embarrassed that I had repaid her rudeness with a kindness.

When I got to the second window, I showed both the receipts and took her food too.
Now she has to go back to the end of the line start all over.
