It also benefits for you too - if you get the message that you gave a person good service and you have good connections with your manager, you'll get the message that you did a good job. When I used to work for a telemarketing company (It wasn't telemarketing...but in the same lines - I can't remember what the term is called. I don't work for them anymore) but when you get good messages back to you, your quality of work improves for sure.

And with that being said, your day goes by faster too!!
