your story twigged an old memory as I read it. Many years back some flatmates friends bought around some illegal smoking substance that the Australian government frowns upon (because they can't tax it) After a few beers and generous puffs of this stuff, I remembered I had to go into town to meet someone, and wobbled off to climb on my bike. I put my key in the ignition, and no lights, nothing, not even after turning it a number of times. The starter would not work, and the whole thing seemed dead. "Flat battery" obviously, and off I walked into town, where I promptly ended up in the nearest pub, and then woke up the next day, at a mates place. He gave me a lift home, and on the front lawn, sat my bike where I had left it. The ignition key was sitting in the fuel cap from the previous day, where I had put it, turning it half a dozen times before giving up. Needless to say, it was a good thing it happened, because I dread to think what might have happened if I had ridden.
