After the armoured car robbery, the crew decided to get rid of Waingro. It's strange that Neil was going to kill him out in the open. There was no plan to even use a silencer, which would have been the smart choice. The gunshot would have attracted unwanted attention. Wouldn't it have been safer to take him to a secluded spot? Waingro manages to escape to exact his revenge on Neil's crew.
shareThey haven't established the trust, if it were not in public, they guy would have run instead of showing up.
shareWaingro was a loose cannon on deck.
Take him to a secluded spot? How? He was too dangerous and unpredictable. Neil decided he had to be to be terminated ASAP.
There was nothing indicating that Waingro was being suspicious at the diner. The crew could've not shown any reaction or just given token, toned down disagreement and finished him off elsewhere.
Even if Waingro was going his own way after the score and didn't have any personal relationship with the other guys they could've still called him for "another job" and baited him in that way.
Good point about baiting Waingro with "another job".
He was, however, dangerous and unpredictable. Neil decided he had to go immediately. It was a greater risk to the crew having him around than to take him in the parking lot.
I love this film but I understand the criticism about this scene. Why did they meet in a family restaurant after the heist? Waingro even talks about having to "get it on". The other guys were cool and not talking.
Why risk meeting in a busy public space? Neil drew the attention of an onlooker reading a newspaper when he slammed Waingro's head on the table. The onlooker retreated when Cheritto stares him down.
Why not meet afterwards in a safe house or an isolated location where they could speak privately?
Good optics, good theatre. But it was illogical.
Yes Waingro killed that hooker and might've been a rapist but i don't think the crew knew that. They saw that he was trigger happy though and probably concluded that this man has issues that go beyond whatever they themselves might suffer from, doing what they do.
Perhaps the implication was that Waingro being the loose cannon might get himself in trouble "out there" and offer up information about them for a shorter sentence. Other than that i don't see how he would be dangerous towards them specifically. They might've needed to kill him off immediately before he does some stupid shit very soon and kills some random dude for saying the wrong thing.
But all things considered i still don't see why they couldn't off him after the score AND not do it outside a diner.
I think that Neil's anger just got the better of him: assaulting Waingro when he wasn't supposed to and rushing to finish the kill. Altough the other guys adapted pretty quickly positioning themselves as lookouts wich somewhat doesn't make sense to me because it all felt like Neil's decision. It would seem more reasonable than all agreeing to kill him in the parking lot beforehand.
We also see this in the end when Neil is out on a personal vendetta to hunt down Waingro. So i don't think danger/unpredictability was the deciding factor - Neil just didn't want to pay such a fuck up.
