Moshe had a very large Judaica store, and, before Chanukah, he ordered a huge amount of menorahs, dreidels, oil, wicks, and other Chanukah goods. In the days preceding Chanukah, and of course on Chanukah itself, he was very busy - people came in crowds all purchasing his merchandise.
Finally, at the end of Zos Chanukah, when the very last customer had left, he looked through his store and saw that every last menorah and dreidel had been sold. Then he began to cry. A customer came in, saw Moshe crying, and asked him why he was sad. Moshe replied, “I had so much merchandise, so many menorahs and dreidels, and now nothing is left”. The customer laughed. “Yes”, he said, “but look at your pocket! This period of the year has given you a great amount of revenue!”
