The compliment received when saying thank you

One day, I had to wait for a while while visiting a friend at a restaurant.

I ordered coffee. After drinking the coffee, I thanked the staff.

At that time, the manager of the restaurant was surprised and asked, "How sweet and beautiful your speech is. Do you take training to speak like this?"

So I said, "I'm practicing the language of love that Mother taught me."

At that time, he said, "That place where I am trusting my mother seems to be a really great place. I definitely want to go and see it later."
