Ok you are gambling just for fun, your friends and neighbors knows that and a friend invited you to his party to be one of the candidates as a councilor and campaign will start in 6 months, now, of course, you need to have a good reputation, will you stop gambling just to have a good image this coming campaign and how will you defend yourself if accused as a gambler.
Being accused as a gambler is not as bad as you think. You just have to control yourself. In which you will not end up to borrow money from other people. If the manager has the trust on you, you don't need to change yourself to have a good image. You don't need to defend yourself as long as you have your control and you don't degrade other people.
