Charon the Ferryman carries souls across the river Styx to the world of the dead but does so only for a fee. It's a business after all.
Check whether the recently deceased has a coin. If they do, print Welcome to Charon's boat!

In the end, let's warn everyone in the underworld (both those in the boat and those overboard) by printing the message There is no turning back.
