The gray worker promised 5,000 yuan, but half way through, he said he wanted 6,000 yuan. What should we do?

He wants to be a rogue, so you can be a rogue too. Promise him verbally first, and give him 5,000 afterwards. You will refuse to admit that you promised to give 6,000. As long as there is no paper contract, you can use this method to treat him. Of course, you can ask whether you can do it for 5,000 or 6,000 in this situation. Come down, so as not to regret the master.
