Random Act of Kindness

Today I went through the In-N-Out drive thru for my family and myself and when I pulled up to the pay window, the lady told me, "A trend has been started. Two cars ahead of you paid for the car in front of you. So that car paid for your meal." I asked, "Okay, so how much is the order for the person behind me?" She replied, "That's just it...there's nobody behind you, so Merry Christmas!" This was completely unexpected and quite the nice surprise!
