I went to a client's house to deliver something today. It's very hot after delivery. Then the customer asked him if he wanted to sit down. Then I said yes, isn't it too casual?

I don't think it is necessary to be so restrained. I should be natural. I should be myself. I don't feel sick. Sometimes what I say is polite, but it can't all be polite. I must learn to look at my face. Many times, I can see it on my face. For example, you went in and sat down today, and finally did one thing, and the customer was unhappy, or you. How about chatting with customers? When you find an opportunity, no one can say, except that you will know more and more about how to do it. I don't know exactly what you do. It's hard to say. I hope you are satisfied.
