I get discouraged when I have to decline working with a client. Usually it's for no other reason than asking me to do something I won't . . . commit copyright infringement.
You see, we (creative dna) do not have the proper licensing to put Mickey Mouse or the Raiders logo on your invitations. Could I? Yes, but doing so would compromise my integrity as a graphic designer. Not to mention cost me expensive legal representation should I get sued. And who wants that?
