How to put a price on healing that is the work of God? Before Monster gazed upon ayahuasca, curanderos did not charge: their work was offset by voluntary donations (food, tools, even money).

But foreigners do not sleep on the floor, they are neither satisfied with banana and fish, nor can stand mosquitoes: they want to be comfortable. Moreover, they do not bring chickens to exchange and if they are given the chance they have the habit of leaving without paying (mixing spirit and matter disgusts them). Thus, the dangerous gentleman Mr. Money (faithful follower of Monstruo) comes to play, and the fearsome Lady Inflation, without forgetting Intermediary, such a bright spark.
