What does it mean to give money to a fortune teller?

Free, of course not. You go to the temple to calculate, or give money.

You let someone else do the math for you, someone else reveals the secret,

Another, it has its etiquette, purifying itself, burning incense, saying spells and starting fortune telling.

What he undertakes is mental labor, and if he has labor, he has to pay.

People reveal secrets because they cannot be revealed, which is not good for others. If you want to pay for your life and incense, you can't let others take it.

Fortune telling is free, and all of them are ignorant amateurs.

So you should pay some money.
