This is just a trend I have personally noticed. For some reason the customers that were referred by friends/family to me never say a thing about my service, always praise. However, the non-referrals or the ones who "found me" seem to try and squeeze the most out of what I do, or they are a little harder to deal with. I wonder why as they are all treated with the same amount of professionalism and good service. Ever happen to you?
