When I go to Israel, inevitably, several people give me shlichut money to donate to needy at the Kotel.
If I can't get to the Kotel, am I allowed to donate this money to anyone else at any other location? Or should I return the money to the donator?
Assume that the donor said, "Give this money to someone at the Kotel," but did not specify either way that I can donate this elsewhere. Knowing something about the people's general personalities, I assume that they don't mind if I donate to a poor person in Tirat Tzvi.
