To me it's when they don't listen. If I go to the doctor and say a certain medication doesn't work for me I wouldn't expect them to prescribe it to me. When I go to a stylist I respect that they went to school to learn how to cut hear, but I expect when I say things like "Don't thin out, cut too short, style straight, etc." that they are going to respect my requests and cut my hair accordingly. I'd also expect if they cannot cut my hair following these rules that they'd tell me up front so I can find someone who can.
