The boatman answered,"One dollar".
The mister wanted to get a lower price."Fifty cents," he said.
The boatman said that was not enough,but the mister got into the boat. The boatman rowed about halfway across the river.Then he stopped rowing and said,"The fare to come here is fifty cents.Please pay me the fare and get off the boat here."
The miser was surprised and said,"I can't get off here." If you can't take me to the opposite bank for fifty cents, take me back to the first place." Than,without a word,the boatman began to row the boat back.
At last the boat returned to the starting place. The boatman turned to the miser and said,"I took you on a fifty-cent trip as you asked, and then I bought you back here again. So now you must pay me ()"
