An old man is selling watermelons... His pricel
Post# of 123672
His pricelist reads: 1 for $3, 3 for $10
A young man stops by and asks to buy one watermelon. "That'd be 3 dollars", says the old man.
The young man then buys another one, and another one, paying $3 for each.
As the young man is walking away, he turns around, grins, and says, "Hey old man, do you realize I just bought three watermelons for only $9? Maybe business is not your thing."
The old man smiles and thinks to himself, "That man originally only wanted one watermelon. But he bought three instead just so he could tell me how I should run my business."
