I don't blame you for being upset. It sounds to me like your getting taken advantage of by the friends of your family. I'm sure they don't mean to, but Dena is right about people trying to get free services. Honestly, I would make a post on Facebook stating that you are no longer cutting hair for anyone living outside of your house and just be honest about the number of people coming to get a haircut and how time consuming it has become. Then ask your family to tell anyone else the same thing.
