"Give to the United Pilots' College Fund, because the mind is a terrible thing!"
True story...was packing up my gear after a gig in downtown Syracuse a few years ago, and walking down the sidewalk w/ a 60lb 88-key keyboard in one hand and a 40 lb amp in the other.. car was about a block away. Able-bodied dude walks up to me as I'm bulling my way to my car a block away and asks for a dollar. I offered him $5 if he'd help me load my gear, which would have taken him 10 minutes (and paid him more than I made, figured at $30/hr, at the crappy gig I had just played). He scowled at me, told me to f@÷@ off, and walked away quickly.
Since then, it's real hard for me to take these guys seriously. I frequently offer to buy them a burger or something if we're near a place, but they never take me up on it. Hmmmmm....
