My friends D.A.'s parents live in Haifa. For years, they would make a sukkah in the yard. There was no room in the house for the sukkah. One year they decided to build an iron balcony. It cost a lot of money, about 20,000 shekels. It was difficult for them financially, but they decided, this is a debt, G-d will help us.
That same year, a neighbor came to sleep with them in the sukkah. During the conversation, the landlord told the guest that he had a serious problem with income tax, with tax coordination. The guest, who worked as a tax consultant, heard this, and said he would look into the matter. After checking and arranging things, it turned out that he was entitled to income tax. The sum was twenty thousand shekels!
