I saw a sink yesterday at my local yard.
Stainless Sink
Brass Faucet
Even had Copper Lines still on it.

I talked to the guy at the yard and said "Gosh man.. whoever turned that in missed out- BIG TIME" he said "Yeah I know.. but most people don't care" I said "You paid them SS price for it correct (Bulk of the metal and lowest priced at .30 lb") He said "I had too" The person who scrapped it could have easily netted around an extra $5 in brass and copper for about 3 minutes of work. Now the yard got the sink, will separate the brass and copper and they paid .30 cents a lb for it instead of the $1.20/lb in brass and $2.00/lb for the copper.

I've said it once and I will again. We all profit off of others ignorance. In my story- it was the yard that profited nicely.. and the people gave it up willingly! Nothing underhanded on their part!
