There is a point where you have to realize that no matter how good you are and no matter how good your service is, there is always going to be a client that isn’t going to be happy with you. Sometimes no matter how hard you work and how much you try, there is always going to be someone out there that you cant please. It kind of reminds me of the managing attorney at my old law firm. Sometimes, people don’t like you and you can’t fathom why. Sometimes you’ll have some clients who will dislike you from day one and you can’t change that.
What can you do? Just accept it and move on and ensure that this type of client is few and far between. You cant be sensitive and try to drown out the criticism by attacking the client. Just accept the fact that there are times that you just can’t satisfy a client.
