I want to send a special product to my customer, and I have little contact with him. I always talk to his people. Now I want to give him some special products. I don't know whether to call or send a message. Because then others don't know that you gave him local products.

I also remember your kindness. To say the least, he just confiscated the gift, and your face is passable under such a small number of people.
