Let us say you entered into the business of being a fake psychic. You advertised your services as totally bogus. This idea started as a conversation at a party, and you decided to test the gullibility of your fellow man by creating an enterprise that was honestly fake.
You had a 1-900 number. Your office consisted of a desk in your garage. Since you were an upfront non-psychic, there was no need to waste money on items like incense, candles, an impressive library of obscure books. The only real overhead cost is in advertising:
"Genuine fake psychic services. I have no ability whatsoever in ESP, predictions, contacting departed loved ones, reading former lives, etc."
The novelty of this idea initially earns you some local press coverage, and the emnity of some real psychics. But the phone calls start pouring in. They don't care if you are a fake, they need help and want answers. But in addition to knowing nothing about psychic matters, you have no training or qualifications in the area of psychology.
As you meet with your first dozen customers, it becomes apparent that all you have to do to make money is tell them what they want to hear, but you know deep inside you are in over your head. Meanwhile, they are lining up at the door. The phone is ringing off the hook. You are now at the point where you will either have to hire some help, or, declare that this joke has gone far enough.
No fair using psychic methods to arrive at an answer.
