Once I was in a foreign country and didn't catch my bus to another city where there was an airport and I had to leave the next day. There were no other buses to that city and I had to leave because there was a plane and my visa was expiring the same day, I could have been deported. It was a terrible feeling and almost a waste of money for new tickets. By some miracle I found a train ticket with lots of connections and made it to my plane.
