They aren't allowed to age discriminate against you. If you have a hard time being a server then try to go into bartending. You could always panhandle for a few days and you could make that amount (or at least a good chunk). Selling your blood plasma nets you like $40, not much but its something. Learn to paint, or just try, and go out and do a painting in public- somewhere that people will be walking past, and strike up a conversation with people in the hopes of selling a piece.

Those are just a few ideas I know they aren't amazing but they are something to think about!
