how do you charge?

I have to think after reading all the posts that wether to charge or not depends on where you are. I know where I am the scrap yards will pick up from a residence and pay on the spot for whatever they pick up. Also people here can put out whatever they want on garbage nights and each morning the town has regular garbage pick up and later they send out a truck to pickup bulk, sofas,ovens,mattresses,refrigerators.....so advertising to charge someone to pick up their scrap doesn't work. Now if i had to hump a stove or fridge out of a basement that is another story, but those calls are very rare.
