Oddness

I was on my way to work today. On the highway I take there is a toll. I didn't have exact change this morning, so I pulled into one of the lanes with the booth so I could get change. I saw that the person in the car in front of me gave a dollar bill. I pulled up, held out my money for the toll taker, and he said that the guy ahead of me paid for me. I asked him if he was serious, and he said yes, to just go. So I did. No toll!
