I argue that "ripping off" is based on the value that a consumer receives relative to the price of the product or service.

Imagine you say: "I will tell you a joke, if you laugh then you must pay me 100 dollars"

If I give you 100 dollars, and you just run off with it, I got ripped off.

If I give you 100 dollars, and you tell me a really funny joke, then I was not ripped off.

Your problem seems to be that telling jokes is virtually free, and the profit margin might be 94%.
