I lent a lad some scaffold to do his soffits on his house once. He told me he'd taken it down and put it back in the yard. Three weeks later there was the scaffold all neatly stacked on ebay. I knew it was mine because he left the sign in the sign board frame and was selling that as well. Cheeky multi story thick tw*tI've contacted the scaffolder to let them know.
Just hope someone would do this for me if the same happened.
