If the superior wants to invite you to dinner or invite him to dinner, what will he say or imply no? after work

Ha ha! This is easier! Then see if he is worth your invitation! If it's worth inviting, you'd better have dinner together. Ask him where he wants to eat first! What do you want to eat! Then lead the way! Just pay after eating. Whether he wants to invite you to dinner or have dinner with him, you can give priority to him. If he doesn't deserve your invitation! Forget it! Remember that no crow is white!
