This will be a short post but it's a true story. It really happened to me.
I was at work one day and it was lunch time. I decided I wanted some chips to go with my usual sandwich. So I went down to the vending machine, put in a dollar, and made my selection. My chips came down and then to my surprise change started coming out of the machine too. One dollar, two dollars... When it stopped, I counted over two dollars in change. Then I realized what has happened.
"I got money for nothing and chips for free!"
