I work for fun a good bit. Since I love welding/fabrication I always offer to help people with fab projects as far away as other states. I'm completely mobile so that helps. Stick welding for a few hours running off the other person's electricity doesn't cost me hardly anything, so I charge nothing. I'm also a sucker for lending a hand moving stuff. I actually love cutting grass and will do it/have done it just for the asking. Call it good Samaritan, or what have you, but I think all good deeds do come back around. I always tell everyone that they don't have to pay me unless they just want to.
