Scrap yards are pits of criminal activity. Someone shows up with 11,000 lbs of aluminum signs and no one bats an eye.
in our machine “job” shop we actually had an employee steal an exotic bronze raw material coil BEFORE it was issued to the machine, to make into parts...it still had the shipping tags on it....Our boss scoured the local scrap yards and finally found it 30 miles away.....to our advantage the yard had video of who dropped it off & we had him arrested...oh yeah - the kids job was material handler, so the missing material was his responsibility anyway...he would have been fired just for that LOL
