Clearly Jabba is more keen on making an example of Solo than getting his money back so it's one of the few plot points of ROTJ that make sense.

Well but it doesn't make sense in ESB. He promised to get right back with the payment in front of his men in ANH. He made a fool of him in front of his men. So deciding to pay him after 3 years (in ESB) is ridiculous and useless because Jabba wouldn't let him go. That is like deciding to commit a suicide.

Not to mention he already had bounty on his head and I don't think he would even reach Jabba before someone would collect it (even if it was in front of his Palace). Just like Greedo would have killed him and collected the bounty, despite Solo trying to convince him he is going to pay Jabba. I mean bounty hunters aren't stupid. On top of that the bounty hunter would just take his pay-off money too.
