Talk to the man on the bench.
Since he’s a fortune teller, you want to know your future. He’s prepared to tell you but first wants to drink some water. Walk to the left and use the bucket from the well to get some WATER. Walk to the right to return to the fortune teller. Give the water to the man and he’ll tell you your future. But is he a good fortune teller?
Alternatively you can tell the man he’s a fake. Result will be the same.
