Honest but not Faithful

A few years ago a couple went into McDonalds and order a lunch to go. They took their lunch outside to eat on the grass and when they opened their bag they found that instead of giving them their food the clerk had accidently given them the money for the deposit from the day before. They took the money back to the clerk and explained what had happened. The manager was so impressed that he wanted the newspaper to run a story about their honesty. The couple quickly said no to that as they did not want their picture in the paper as they were not married to each other but were actually having an affair.
