When I was in 12, I volunteered to help feed the poor at a soup kitchen. When I was in high school, there was a mandatory volunteer requirement of 40 hours just to graduate. Volunteering isn't disgusting, it's valuable experience. It's no different than putting volunteer experience on a resume to get a job. Volunteers are in short demand; it'd be much more disgusting to deny help just because their intents aren't purely altruistic. Heaven forbid you help someone and help yourself at the same time.
