Come to the store, put the bowls of ice sand neatly in the quilt, separate them with a clean towel, and cover the quilt tightly, leaving no gap.

Everyone is curious to see the action of light rain, do not understand what light rain is doing.

Koizumi directly doubted: "Xiaoyu, what are you doing? Why do you put the ice in the quilt so that the ice will melt quickly?"

Xiaoyu popularized knowledge to everyone, "this quilt is warm in winter, right? If it is covered with ice in summer, it can keep cold. This is called adiabatic transfer and cold transfer! "

Looking at everyone's face, he said directly: "anyway, you know, this can keep the ice from melting."

Stand up, smile: "Dad, mom, then my brother and I will go to the restaurant, you see the shop!"

"Be careful, be safe!" Zhao Qun quickly asked.

"I see!" Koizumi picked up the wooden basin on the ground and walked out of the shop behind Xiaoyu.

They soon came to the back door of the restaurant, where Gao Yuan was already waiting.

"Here you are. I've already told the shopkeeper. The shopkeeper said to give you a bowl for each table, and let you taste it!"

"Well, OK, let's go in!" Xiaoyu, when they come to the kitchen, brings a bowl of smoothie with them.

Xiaoyu, Koizumi and Gaoyuan stood at the stairway to observe the attitude of the guests and see how they reacted.

At the beginning, everyone hesitated. It was said that it was free. Soon there was the first one who dared to eat crabs!

After the man finished eating, he cried out that it was delicious and let him serve another bowl.

Small two immediately forward, "this is the store's trial products, each table only one, and only 20 free!"

The man slapped the table and yelled, "give me another ten, I'm not bad for money!" A purse was left on the table.

Others can't help but wonder what kind of good things are worth "inspiring the masses" when they see such a fierce reaction from big men.

So curious, they all began to eat the gift on the table - cold smoothie.

As soon as they ate it, everyone cried out that it was delicious. It was just delicious. Let the boss give them more.

The shopkeeper quickly stood up and said, "dear guests, today's thing, because it's not our shop's, is gone."

Xiaoyu immediately stepped forward, "but our" fresh vegetable cold drink "shop is always welcome to taste. There are different flavors to choose from. The address is at Yongchang 7, two blocks away from here."

Koizumi and Xiaoer went back to the shop to pick up the goods because the guests were arguing.

Xiaoyu stayed to talk with the shopkeeper.

"Miss Zhang is worthy of being a good business man. It's really daunting to show off her hand casually." Shopkeeper is to have to sigh, this wench is really too clever.

"The shopkeeper's reputation is too high. It's all opportunistic." Xiaoyu smiles.

"Miss Zhang is modest. Now let's talk about this cold drink. I want to take it from you and sell it in the store. What do you think?"

"It's easy to say. You helped me just now. Well, I'll sell it to you at 20% of the selling price, so that everyone can make a little profit!"

The shopkeeper nodded, 20% discount is OK, originally he thought 10% discount is the most.

If they get it back in this way, they have to raise the price, so that they can earn more and be cost-effective!

"Thank you, Miss Zhang!"

"Peace makes money!"

They laugh at each other.
