People have no clue what it takes to haul their stuff

I get calls all the time to haul away scrap. Snowbird season is the busiest. This morning for example a lady texted me saying she had a large load of scrap metal. I wrote back telling her that scrap prices are really low and unless she basically had tonnage it was not worth my time. She responded telling me what she had which consisted of old patio chairs and chain link fencing and some other stuff. Maybe a couple hundred pounds. She was not to far from my home but when I declined she wrote me back and was mad. She went on to tell me all about what the city wants to haul the stuff away and since I had an ad looking for scrap to haul for free she felt I was obligated to haul her stuff. She black balled two of my Craigslist ads and got them removed. People amaze me and have no clue what it takes and costs to haul their stuff for free. I had tried to charge a fee early on but in my area every illegal alien out there hauls scrap. I have scaled way back on my hauling and dropped the Craigslist ads. Just not worth it right now. I just haul for three regulars. One loads me up with about a thousand pounds or more each time. The others are aprtment complexes.-****(Guess I should have been more specific. My CL ads are very specific with load limits. What I will and will not pick up and most of all my pick up area even providing streets that surround my area. I even list what I get for scrap steel. All people see is free. They do not read the ads. It was suggested by a member to charge half of what the city charges. Tried that. Like when I tried to charge a fee. It did not happen).
