OK OK I get it!

Got to the Tire Shop to pick up my car after swapping my summers for snow tires. There was only room in my trunk for two tires so the tire shop put two tires in the back seat of my car. They were in nice clean white bags, so I didn’t think much of it until I got home. I felt a slight hesitation when I went to pull one of the tires out of the passenger side rear door. When I got it out I could see a tear in the leather upholstery. “Where did that come from?” I wondered. To make a long story short…   I ran over a screw and it was sticking out of the tire tread. Nobody noticed it because the tire still held air, but it snagged the seat on the way out of the car and ripped my beautiful leather.
