NPC: hey buddy I know you just killed the world ending dragon but my shoe string broke and it would be dangerous to for me to walk to the other side of town to get a replacement string. Can you go get me the string? If you do this for me I give you an item that you have an inventory full of that you won't use because you are saving them all for a tougher fight, even after beating the secret ultra hard boss and the final boss but there might still be a need.

Me: hell yes I'll get your shoe string on the other side of the world if I had to. Don't worry about giving me any money I maxed that out hours ago and can't find anything to spend it on. Sure I'll take the item, you never know when you might land in a fight where a potion that heal 1% saves me. Sorry about not talking to you 100 hours ago your character model looked kind of plain so I didn't think you would have quest for me.
