Very many years ago, our government building was having a refurb and some corrugated roofing panels were being replaced. A memo went around asking if anyone wanted any of the 30 or so old ones. There was only me and an older guy interested in them. I was worried this guy would try to take them all [he was a bit like that!] - I only wanted 6.
So I loaded 6 into the back of my car after work, one at a time as they were heavy, in the underground car park. I was quite blatant about it as I had no reason not to be.
About 3 days later there was an announcement at work asking if anyone knew where 6 NEW roofing panels had gone!!!
No I didn't ever confess or give them back. It makes my blood run cold when I think about it now and how lucky I was that no-one ever saw me to report my 'theft'. Luckily it was way before CCTV.
I still have 4 of them too!!! LOL
