That makes absolutely no fucking sense.
Why do I need to volunteer somewhere to complain? Better yet, why would I volunteer somewhere I help fund? It is the fucking people who are using the service that should be volunteering. If I ate at the soup kitchen -- I would take a day out of my homeless life to help serve at the food kitchen. Do you know how many people do that? Probably not that many.
Yes, I agree taxes keep our country running. But we do not need to go into a fucking unrealistic budget deficit just so you can get a fucking deal on windows -- a deficit I will have to help pay for later. If you are so into volunteering give your window rebate to the homeless, douchebag.
