I dealt with this when I was younger and built custom cars. Every car builder I learned from has, so I wasn't surprised when the same thing happened after I made my first "app". The most common denominators are they have nothing more than a concept in their head (nothing on paper, no artistic renderings), want you to invest your time making their dream product, promise you'll both get very rich, have no skills to help make it and express no desire to work on learning them, and they'll be the corporate CEO.
