If you just become the store manager and the manager invites you to dinner, how should I propose a toast and say something?

On the premise of being polite and modest, talk as much as possible and find more topics, even if it is useless. Of course, don't just say it yourself. Ask the leaders' opinions and opinions frequently. In short, it is a word, interact with leaders more and don't be silent. Put yourself in the leader's shoes and make him feel that you are natural and easy to talk to.
