My other half has been asked for 500 Euro by friend A to help friend B. A is also giving 500 as is apparently somebody else (it's a very convoluted story). What is a polite way of saying no? We actually have no problem giving the 500 to the level of not wanting it back. But I have a problem of giving it to A (the money will definitely go to B) as I don't trust his ulterior motive (could be wrong) and I feel my other half would feel like he was being mean/tight - macho thing to friend A if he doens't stump up. Money cannot be given directly to B (can't deal with money).
