Suppose you take your car to a body shop to have it repainted. When you go to pick it up, you are not happy with the quality of the work, but the body shop refuses to release the car to you unless you pay in full for the work. You give the shop a check in the amount requested, and on your way home you stop at your bank and request that the bank stop payment on the check you have just written, an action you decided to take when you were writing the check. Have you acted ethically?
