In my opinion, his quality determines that he has little room for development. So for such a leader, you don't need to curry favor with him. Besides, is it useful to curry favor with him? Even if it works, the monthly salary increase is not enough to cash him in. There is not much difference between such a salary increase and no salary increase. For me, it's best not to increase it.

If the other party asks you to bring food again, you can directly say to the leader: "Sorry, leader, I forgot to charge money in my meal card (or forgot to bring my wallet). I want to borrow someone else's money to buy lunch today, so I can't bring it to you. " This sentence is obvious. He should also take out his meal card or money wisely, and may even give you all the money you brought him these days. If he gives you his meal card, you can also pay for your meal.

To tell the truth, we don't care about the cost of this meal, but as a leader, his practice is really disgusting. How can such a person be a leader when he is so stingy with a meal?
