If you listened to radio, you would have noticed the DJs would vanished from the airwaves and appear back at another station. It would be quite common here since the circle is small. Just that somehow when one decide to jump ship to a competitor, he will bid the listeners farewell and would say he is going somewhere or will doing something else. Then after probable a few months he would be back in someone else's studio. While I understand it could be part of a contract that you can't announce that you are going to the other studio, it just isn't right to say something else. Just say good bye and that's it. It just sound wrong. At least that's my opinion.
