The only option in the end of this starter delivery quest is to Bluff for more gold. It would be nice if any other dialogue option was available. I can imagine not everyone is going to try to ask for more money.
I like that the bluff doesn't actually work, I think its hilarious when npcs have conversation skill check hooks and when you try them they laugh in your face!
Great quest.
Agree that not all PCs are liars.... fixed.
