A man goes to get his check and when he opens it he discovers that his employer has overpaid him by $200. He decides not to tell anybody and keeps quiet. At the end of the following month when he opens the check, he sees that he’s been underpaid by $200. Fuming, he goes to have it out with his employer. “Sir, I think you’ve made a mistake on my check.” “And how do you figure that?” his employer asks. “It seems I’ve been underpaid by $200.” “So?” “No disrespect Sir, but I want my money.” “Last month I overpaid you by $200 and you didn’t complain so why now?” “Well Sir, thing is I don’t mind if you make a mistake once…. but if it becomes a habit I have to say something.”
