True story, I posted up outside a sandwich shop one time, on my way of town on a long ride. I had grabbed an old lock, one I thought I knew the combo for, but when I came back out with my sandwich, I couldn't unlock it even after several minutes of trying. I walked back home, about 2 miles, got in my car and drove to the hardware store. I explained to the store employee what happened an requested the purchase of some heavy bolt cutters, for which I had to speak to the manager. After explaining my situation to the store manager, he helped me pick out the most affordable cutters likely to do the job. I then drove back to the sandwich shop, popped the trunk, got out and stole my own bike back from myself in broad daylight.
