If you want to keep players on their toes, introduce some person they're really not expecting to see in the current location/circumstances. It could be someone friendly, or hostile, but the important thing is that they're unexpected.
Like when you bump into a friend or relative in a bizarre place where you'd never expect to see them. You know that momentary flicker of panic as you try to comprehend what is happening, until you realise who it is you've just stumbled upon? Yeah, capture that feeling.

Oh dear. These two don't seem like the type to do things quietly. I think the odds of Finn getting caught and a bar fight happening just went way up. Burly alien doesn't exactly seem to grasp the concept of subtly or properly receiving reports. If you tell the spy what you already know, they can tell you lies to benefit themselves if they know you don't have a way to confirm, and I don't think Mr. Shut Up is smart enough to see through that.
Hmmm, Kanata pointed these two out as people for Finn to talk to. Now I'm wondering if he's trustworthy or not. Maybe "death sticks" is just spy talk that Finn should know if he's a proper spy, and there's no actual callback reference intended. In-movie, it makes more sense if Finn went to get drinks, then sat down here to give a quick report while waiting for the bartender. There hasn't been any other great times he could hand off or send a report without leaving suspiciously or getting caught up to now.
I almost thought Red Armor was one of the guards that showed up with the Guavians too, but the face plate design doesn't match. The color is different too looking closer between them, but that might be the lighting on the ship. That would have been an extremely crazy twist if they were the same though, and would have had me start wondering if Mr. Shut Up was a gang member as well.
Finn: I go see the guys about the death sticks.
GM: One is clad in red armour, with wicked horns on the sides of his helmet. The other is a burly alien with a peg leg.
Finn: Hey, you guys don’t happen—
Quiggold: Shut up. We’re First Order. Lord Ren wants your report.
Finn: What? How did—
Quiggold: Shut up. Every agent we have is on the lookout for you. Whaddya got?
Finn: Well, um... Poe, the pilot who—
Quiggold: Shut up. We know he’s dead. What else?
Finn: I’ve hooked up with Han Solo, the old Rebellion general, only he’s going by Yanni now. And his daughter Rey.
Finn: They have a map to Luke Amidala, but it doesn't match known records.
Quiggold: Shut! Up!
Quiggold: By which I mean keep going.
