Firstly, I LOVE the 12 - the bendy bus massively cut journey times on that route, although that seems to have ebbed away over the past year or so. But I have, once or twice, not paid my fare on there. Not intentionally, but having got on the bus thinking I had a juiced-up oyster card, finding that I didn't, and having the choice to get off at the next stop, go and find an oyster topper upper and catch the next bus, making me late, or not. I didn't do it. You can shoot me if you like.
