At college people would get paid to hand them out. Mostly starving students would do it to pay for food or shelter. Pretty sure they got paid according to how many they handed out, so I'd usually take them if it was someone my age handing them out. If it was someone older, or someone crazy-looking, I'd walk past without making eye contact. My friend would take one from anyone, walk straight to the nearest trash can (in view of the person who just handed it to him) and throw it away. I'd never do something quite THAT rude, but it's pretty rude to force someone to take your fliers in the first place.
