As far as they are happy with your work?

One day in June, I worked afternoons in his shop, came to my table, fourteen-year- boy, Tommy, and said, 'Hi! ' .
- Mr. Rafla, can I use your phone? .
- Of course, Tom, what a question!.
He dialed the number, and I heard: - Good morning! . I've been mowing the lawn to make some money, as well as the installation of fences. I would like to know if you are not interested.
He paused, listened to what he said and continued: - Yes, it is clear. And you are happy with their work?.
There was another pause. - Got it. Well, you do not mind if I call you in about a month? .
And Tom hung up the phone. I left the table and said, ' Tom, I'm sorry, but I was there and could not help hear your conversation. I want to tell you all what you said on the phone was just fine! .

And then this, he replied: - Oh, Mr. Rafla, deal - I made ​​a long time. It was one of my clients. I just checked how much they are satisfied with my work!.

Did you check whether clients are satisfied with your work and how?.
