I know this is wildly off-topic, and I'm sorry to take up space on the Cat. I'm asking here because there are so many quirky minds and world travellers, as well as helpful, nice people.

I heard years ago about an Indian city that had a high rate of non-payment on bus fares. So it instituted a lottery on the bus tickets. The rate of non-payment plunged; in fact, bus tickets became a hot item for trade! But I can't remember what the city was, or find any reference online.

Does anyone know what city it is or was, and whether the scheme is still going? I have a feeling it was Bombay/Numbai, but it's only a feeling.
