In The Force Awakens, Han Solo's spaceship is entered by a gang of criminals, who demand their money back which Han borrowed from them.
However, Han doesn't have any money, he invested it all in acquiring those rathtars he is now on his way to deliver to King Prawn¹. So he doesn't have it now, but presumably he was going to pay them off after he got paid. And the criminals know it.
But then they go off into a tangent about how Han cheated on them by also borrowing some money from the Kanjiklub, which doesn't really make any sense. I mean, so what? Who cares if Han borrowed money from multiple parties? And as it turns out, they're not on bad terms with the Kanjiklub, they even hired the Kanjiclub themselves to have more men to beat Han up with.
So then they say, matter-of-factly,
"OK, we'll take the droid then", which they obviously knew about, and it turns out they were in league with the First Order all along.
So, my question is, were they really in it for the money?
Or were they simply hired by the First Order, with, presumably, promises of better payment?
¹ Yeah, I know, you can look the real name up if you want.
