On one of the baseball card sites I frequent, the author posted a message regarding the golfer who recently turned himself in for using a ball that was a 'prototype' ball. He did not realize he had used the until he was back in his hotel room after the round of play. His use of the ball rendered him disqualified.
The question posed by the author was "How honest are you?" What you see below was my response:
At the end of the day, we have to face ourselves in the mirror. My wife and I recently shopped at Target. After our purchases were rung up, I realized that the total was in no way in line with what we bought (even though every item had triggered a 'beep' on the register). Sure enough, there was a bag of items totalling more than $50 that we had not been charged for. We talked about it, and I ultimately decided the right thing to do was to go back and pay for the items. At the next store, my wife had forgotten to pay for an item she was holding. She immediately went back and paid for it once we realized she hadn't been charged for it.
We don't always do the right thing, but sometimes we just have to...
