I broke into somebody's shop today!
I found some nice coated 21 mm. plywood for boxes in my horse stable on E-bay. In the opposite end of the country, but about $650 cheaper than I could get them local, plus I could pick up the rubber mats for the floor on the way back and save $250 in shipping on those. That made it worth the drive.
After a 5 hour drive, the seller isn't there as promised and does not answer his phone.
I waited an hour, then popped he big sliding door to his shop off the rail with a wrecking bar from my truck, loaded the plywood, left the money, popped the door back on the rails and went home.
I sent the guy an SMS explaining what I'd done, and this evening he called me and apologized for standing me up.
I sure felt a bit weird breaking into his shop, but he was completely cool about it ( not that he has much choice)
