Excuse me, I'm from the finance department, a finance section chief, myself. If the leaders of other departments come to the finance department for reimbursement, they will stop by and lead with us.

If it was an important secret, I wouldn't tell it to your face. Otherwise, A knows that you and your section chief are of one mind and one of their own, so they are unprepared (usually the former). Because of the signature this time, you can wait for him to listen to it by the way. Don't let him know that you are listening on purpose, but later your leader said that you can leave if you have nothing to do, so it is estimated that the following content is very important. If you sign his name next time, you should get off work quickly. There is no need to listen, or say sorry. I'm sorry, let him sign it, so you should go. Don't worry, the leader will tell you whether to stay or not.
