Perceptive Reader, Think about it.
Just because a person feels your life and or what you do as a professional is not valuable; then they are still maneuvering you daily to provide that same service you charge for; then guess what? Through there own efforts they have/are showing you they do value your services; but have gotten over on not reimbursing you with the wage like they do for people/companies they do value.
Any Talent, Hobby, or Skill, you do for wage past your initial free samples/demo you should be paid for it.
It’s one matter to give it free by agreement to this person or that one.
It’s quite another to be a well established person, firm, or corporation finding ways to swindle such services out of a professional when you know funds are allotted in the budget for vendors and miscellaneous services needed for the business to optimally keep functioning.
