Or maybe, and I'm going to just throw it out there...

...Finn and Rose use an actual parking lot, don't get thrown into a maximum security jail cell for a traffic ticket, get the actual guy they came there to get, he actually does the job properly, and they all win and go home for space waffles.

Like they are explicitly told it's Maz and one other guy who can do it. Then they go in anyway with the first guy they meet even though he constantly throws up red flags. Then it's meant to be some kind of shocking betrayal that this random man off the street fails to do the thing the story already said he wouldn't be able to do and sells them out the way he'd been claiming he would the entire time.

The story assumes he's another scoundrel like Han Solo, without establishing him having Han's hidden depths or heart of gold outside of literal minutes before his betrayal. Or else it assumes he's another guy like Lando who's shady but has a reason to be trusted, even though unlike Lando he doesn't have an "in" in the form of an existing friendship. He's just some dude who happened to be there.

They never even learned the guys name. The audience didn't really have any reason to trust him beyond him just kind of being on the screen.
