Am I confused about Charity Fundraisers? Nobody gives any money

Oh, that makes more sense clicking on the host but earlier in the game I would get all these requests for my sim to make a donation and she only had like 200 Simoleons but I'd go ahead and say "sure, here's 1000 Simoleons" and then it would accept it but not sure where they were getting the money from cause it never changed her bank account and it never would demand she pay it but it did improve her reputation as a generous sim. Very strange. Probably is a mod conflict.
