Sorry for the loss of scrap but if you took the time to set up these pick up spots you should have made sure that the accts knew where to put the stuff so this didn't happen. I know from experience that sometimes when you get that first " yeah, sure I'll put some stuff aside for you" that the little details are missed like where to put it or having a set day to get the stuff. Try to schedule pickups on non trash days. These are when most scrappers are out curb shopping and if your stuff is on the curb then it's fair game.
