There are lots of charity boxes from different organisations put out on a table in the foyer of our synagogue on Purim.
The wardens have attached a note that says that boxes not taken away by the end of Shushan Purim will be emptied, the contents given to the shul and the boxes disposed of.
Is this (a) in the spirit of Judaism (b) within the laws of Judaism?
While I understand that anyone can make conditions to the entry and free use of space in a building, could it be that to appropriate charity funds intended for one receiver is prohibited (or at least slightly in the spirit of Sodom) even under such conditions?
