I’m sitting here wondering what specifically Julian doesn’t like about the carpet, is it the colors? Is it because he recognizes what type of material the carpet is made of, and that the com panels explode so often that it singes the fibers and leave an awful smell he can’t stand when they are in battle? Or is it because they actually even PUT carpet on the bridge and possible his medical bay, getting blood everywhere and staining everything. In the end the only way to get it out is to replicate the damn carpet patch to replace it. (A task Garak is assigned to do, which Bashir never hears the end of from Garak when they share lunch) So it’s not just the carpet he hates, it’s the entire events that are made because of the damn carpet. Why can’t they have non-slip metal flooring like they did in the old models of space ships? Some easy cleaning and functionality is all Bashir is asking for.
Meanwhile, Chief O'Brien’s face in the second gif leads one to believe that he’s only just now realized there IS carpet.
