What happens after the last bus?

Do people wait, not knowing if the last bus has passed them by then get frustrated after half an hour with no bus in sight?

How long would it take for them to realise that it's too late?

The last bus is never empty - people do go home only that late at night. People rushing to make it back home in time, people who know that it's their last chance for the night.

Most people make it on to a bus. But what about those who miss the last bus? Who will walk home with them?
