Accidentally Gave Away Some Scrap

So I picked up some aluminum chairs and a leather office chair driving around today. They all had free signs on them, and I didn't take them off because they haven't been a problem. Anyway so I park in the student parking lot at my high school and later that day I discover that my office chair was gone! I was ready to report that my office chair was stolen, but I realized that I left the free sign on it. Someone took my chair thinking I was giving it away for free. Stupid me!!! :facepalm: Thankfully my heavy aluminum chairs didn't walk away.
