An old man is selling watermelons. His price list reads
1 for three dollars 3 for ten dollars
A young man stops and asks to buy one. “That’ll be three dollars” says the old man.
The young man buys another one, and yet another one still, paying three dollars for each.
As the young man is walking away, he turns, smiles and says – “Hey old man – do you realise I just bought three water melons for only nine dollars?
Maybe business is not your thing.”
The old man replies – “People are funny. They always buy three water melons instead of one, yet they keep trying to teach me how to do business.
