I like a lot of the central ideas here, looking at the slightly bigger picture of what you're going for in the ideas thread, this seems like it could be a neat series once it's more fleshed out.
I have some issues with the structure and pacing. There's a lot of banter between Rodney and Polk, and it's broken up by descriptions of their behavior, which can be good. But that's all those descriptions are doing. The narration isn't underscoring or adding to the conversation or making us more familiar with these characters, beyond them being tired field agents. They have a bit of difference in their personalities, but the way they speak and some of the actions they're taking feel a bit too similar. It seems like you want them to have a buddy-cop vibe. For the sake of that, describing them more in appearance, making their mannerisms more distinct and giving their statements more context could be very helpful.
For instance, Rodney seems more philosophical and laidback. Polk seems a bit more clinical and by-the-book. I like the contrast of the more uptight character wanting to be a deskjockey with the easygoing character wanting to be the rough-and-tumble field agent. While it makes some sense for the scene, introducing both of these characters jamming food into their mouths makes them feel too similar. With no description of what they look like, or how they act beyond their immediate actions, they muddy together a bit too much.
This extends further: Diva-Scent is a teenage girl (if you're not inoculated against memes). That's a broad category! How does she dress? How does she look? How does she behave? The slight valley girl edge comes through in her dialogue, but it's not enough on its own.
Story note: Polk really took his partner not being immunized against memetics in stride when they're clearly about to go deal with a memetic effect they don't understand. Diva-Scent's appearance even carries through electronic media, apparently. Since Polk seems more uptight (and is looking for an excuse to get out of more dangerous fieldwork), it sticks out as odd that he'd just go "Oh, okay, you're putting both of us in danger while we approach an event we don't understand," without even letting dispatch know. For the sake of the story, I would consider having your trash crew look human on film, even to someone who's inoculated. That way, by the time your characters realize it's important that Rodney isn't immune to that effect, they're already in the area and dealing with the situation.
A couple of times, you gloss over things that feel like they should be more descriptive. Polk and Rodney realizing they're seeing two different things is one of those times. That feels like it should be focused on in character instead of glossed over in a sentence. There's also very little scene setting in places where it feels like it should be important—I had to reread multiple times to understand that there wasn't any trash when they arrived to the area the volunteers had been cleaning up.
Last mild quibbles on writing style:
-You can just say "Rodney said" or "Polk said." A big chunk of the dialogue is rendered like "Polk improvised" or "Rodney interrupted." Reserve the more specific words for places where they're needed, to make them impactful instead of distracting.
-You use the word "apparently" a lot while directly describing something—you don't need to do that, you're already telling us exactly what's happening as the narrator. You can use "apparently" when it's something the narrator is alluding to. Example: If you are describing a car crash, describe the car crash. If you're describing two wrecked cars on the side of the road, then you can say "Apparently, there had been a car crash."
-This is personal preference, but I recommend avoiding ellipses as much as possible. Places where you would put ellipses are generally better served by including more description or restructuring the flow of dialogue to avoid them entirely. If you're going to use ellipses, use them at the end or beginning of dialogue to indicate awkward pauses or speech fading in or out as the description demands.
-If you can, read your dialogue out loud and see if it feels natural. Several portions (particularly when they speak to the teens) feel a bit awkward and stilted.
