You can/should/may/will think Fortune Telling as a "BUSINESS", an "INDUSTRY". How can you promote yourself (as a solo practice), marketing (free sampling) collecting fee(like, A/R), Customer Management(for repeated customers yearly). Most good fortune teller have experience of 20 to 30 years of professional and business experiences.....
"Customers" are looking for what they have seen on movies. That needs at least 20 years of experience. Paying fee is small issue in Fortune Telling Business, if the fortune teller can give CORRECT information to their "clients".
Hope you can tell the difference between "customer" and "client". Fee is a small/trivial concern in Fortune Telling for clients' million-dollar question and/or decision, if Fortune Teller has "confidence" of what he/she says.
For people in one side of Table(or computer),
You pay what you get, you get what you pay.
For people at another side of Table(or computer)
You are paid by what you give, you give what is paid.
A simple business consideration....
Please check the meaning of "consideration" in Business and Law.
