You, already impoverished and suffering from hunger and cold, stand on the platform waiting for a train, not knowing if you will be able to catch one. At this moment, suddenly, a BOB train comes into the station, and you don’t know where it will go, whether it will be better or worse. You also don’t know how long it will take for the next train to arrive, if it will come at all, or if it arrives, whether it will pull into a platform far away from you. This is whether you will take the BOB train.
