There are two people. They both sell ice cream, and their business is very good.

one day, the first man drove to a place, and the second man came. They all called the children to buy ice cream. The second man secretly put a piece of paper on the first man's car, and then all the children went to the second man to buy it. It turned out that the paper said:

Delicious today:

Snail leg cauliflower sweet corn salad dressing

The first man was so angry that he moved to another place. But he didn't notice, and the second man unplugged the power cord of his freezer.

however, the second man came again. But the second man just came and left. The first man thought he was afraid, so he opened the freezer door to sell ice cream. But just after opening the freezer, melted ice cream water flowed out of it. The first man angrily went home to exchange goods.

after exchanging the goods, they met again. The first man took out a sign, "All ice creams are reduced by 25 points".

"Then I'll drop 31 points!"

"I drop 35 points!"

"Then I will drop 45 points!"

"drop 51 points!"

"61 points down!"

"drop 91 points!"

"I'm free!" The second man said.

As soon as the voice fell, all the children nearby ran to the second man and snatched his ice cream.
