Eating noodles in a small restaurant is too authentic. If you want to learn from him, how can you talk? He is an ancestral craft,

Never learn a trade as soon as you open your mouth. People will think that you covet his secret recipe.

Ask him if the restaurant needs manpower, say that his work is not good and he wants to change to an environmental protection job. I think the boss is very nice and wants to work here.

That depends on your interpersonal skills. Be diligent and take the initiative to make him trust you. Don't worry about this step. About three to six months. But if he is still wary of you in a few months, you can give up. If he trusts you very much and the restaurant business is good, encourage him to open a branch. Before that, you have to find out whether the restaurant is really popular, whether it will make money, and don't hurt the boss. Find a good geographical location and give him advice. It is best to stay away from his shop, because he will be too busy. Naturally, he should take care of the people he trusts most.
