I have a small coffee. The director himself, the subordinate. The client comes, the girl. I said good morning, asked what coffee she would like to drink, and so on. Standard, in general, phrases, but I say immediately I am really pleased with each customer and politeness is not limited. I fulfilled her order, she calculated, I said goodbye to her, wishing her a good day. The girl turned around and looked badly at me and asked, "What are you so polite?"I honestly even cried out. She, all with the same look, shrugged, repeating after me "parents raised" and went out knocking the door.
