I was visiting with friends at the local coffee shop over the weekend and a friend of mine said "I used to get all upset about things to the customer service person and I shouldn't have, I was only killing the messenger." She noticed after a few years of trial and error, that if she was nice to them they were more willing to help her out with her problem. So now she starts by being nice to them and explaining her problem in the most calm and easy going manner as possible. Now she hardly ever has a problem with the customer service person and they do truly listen to her.
