Almost all my policies are on my website, so people can see them before contacting me. I have had some people tell me that they found my website to be scary, because of my policies, but they are all common policies. I feel that if someone is scared or uncomfortable with my policies then I don't even want to waste my time interviewing them. I make it very clear several times through out my interview that I follow my policies, no and's ifs or buts about it. After saying that I do hold the right to let a policy slide if I so choose, but I never let a client know this.
I am every good at letting people walk all over me, but for once in my life I am my own boss and I WILL NOT take any shit from anyone. That's why I make sure I am very clear about my policies (having them on my site) before I even meet people.
