I give to things I want to support, or that I believe make sense from a business point of view. I do not fear saying no either. I do it politely, and tell them that I would love to give to every great cause that comes to my door, but, that my business just does not have that kind of community support. I have to watch my pennies.
On edit: Any friend of mine who asks for support like that and gets a no, and many have, if they feel they cannot accept that gracefully, then I know we were never really friends. I simply cannot throw $200 at every good cause.
The SS Platypus, sails again, to the support of the Vets!
