Magic divination pills

An old woman down by the market near the countryside is announcing her new product:

*Magic divination pills! Come get your magic divination pills!*

An intrigued tourist approaches the old lady.

"What are these pills you're selling?".

*Magic divination pills mister. You eat one and you gain a one time divination power to guess anything. $1 per pill*

"What if they don't work? What if I don't guess anything after eating them."

*You pay after you guess, you don't guess, you don't pay*

The tourist thinks it through. If the pills work, he could guess the winning lotto numbers, if they don't work then there's nothing to lose. He orders a pill and eats it. Almost immediately he falls unconscious to the ground.

When he comes around he finds his wallet is missing. The old lady is still at the stand selling the pills.

"Hey you! You thieving lying old hag! I ate one of your pills, guessed nothing, and got my wallet stolen. These pills are pure bullshit!".

*You guessed correctly mister! Made from our finest bulls! That'll be $1*
