There is a shop selling puddings. Every Christmas, many of these delicious foods are arranged in a row for customers to choose. Here you can choose the pudding that suits your taste best. Even the store lets you taste all kinds of puddings before making a decision.

I often wonder if there will be some people who have no intention to buy at all, taking advantage of this discount. One day, I asked the salesgirl this question and learned from her that it was indeed the case.

"For example, there is such an old gentleman," she told me. "He comes here almost every week. He has tasted every kind of pudding. Although he never buys anything, I guess he will never buy it. I remember him from last year, even the year before last. Well, if he wants to try it, let him come and welcome him to try it. In addition, I hope there are more shops for him to taste. He seems to really have this need, and I don't think they care about this little thing. "

Just as she said this, an elderly gentleman limped to the counter and began to look at the row of puddings with interest.

"Well, this is the gentleman I told you about just now," the salesgirl whispered to me. "Now you just have to look at him." Then she turned to the old man and said, "Would you like to try these puddings, sir? You can use this spoon. "

The shabby but very neat old gentleman picked up the spoon and began to taste it one by one, only occasionally stopping to wipe his red eyes with a big broken handkerchief.

"This kind is very good."

"This is not bad, but a little tired."

One thing is obvious from beginning to end: he sincerely believes that he may eventually buy a pudding; I'm sure he doesn't feel that he is cheating the store at all. Poor old man! It is likely that he has been down and out.
