Stick Out One's Neck

How come they’re asking me to act as their guide through the jungle?

Evidently they think you’re the only one who can lead them to the lost temple.

That jungle has danger lurking around every corner. Why should I stick my neck out for them? They didn’t pay me for my services.

They know that you would be taking a great risk and could possibly get hurt, but you’re the only one with enough knowledge to take them to their destination. I’m sure you’ll be amply rewarded.
