Answer the question. (根据以下内容回答问题）
Cody liked the freedom that came with his first summer job. He worked at Mitchell's Farm where people could come and pick the corn, berries and tomatoes out in the fields themselves. Then they'd bring their produce to checkout stand, where Cody would weigh it and charge (收费) the appropriate price. Mr and Mrs. Mitchell were usually busy somewhere else, so Cody was trusted to manage the stand by himself.
For the most part, Cody obeyed the Mitchell's rules. When someone asked for a discount or a sample, Cody said no. But he did sometimes change the rules for friends, much to their delight.
"Go ahead, taste a few berries before I weigh," he'd say when it was someone he knew. It was against the rules to eat something before you bought it, but everyone wanted to.
One day, a man came to stand with a basket of corn he had picked. Cody weighed the ears of corn and told the man how much it cost. The man looked confused.
"But I was here yesterday, and you told someonethat for every five ears you buy, you get one free," he said.
Cody had it in his memory. He had indeed offered that deal to the Thomases, who happened to be his neighbors. Now he felt sad about it. He saw Mrs Mitchell working close by. How was Cody going to explain that he had given a deal to those he knew while he made everyone else pay full price?
The man saw that Cody was looking at Mrs Mitchell," Is that the owner? May I speak to her?" he asked.
Cody thought about offering the man the same discount, but there were people in line behind him, and they were carrying corn, too. Cody hung his head and walked over to seen Mrs. Mitchel.
