When I first got involved in the Phil's it was a shock, asking for this and that and not being use to this the answer was nearly always a big fat NO,.
But we all mellow and for the sake of our partner's we try to help.
Our way of dealing with cash help is I am in charge.
They ask Emma to ask me to borrow some amount, we then agree a set time to pay it back and if they and myself are happy then the money is sent, so far it's all been returned on the dates too, that's except one person who will not get anything ever again.
It works for us, but maybe may not work for you
