Hey! She was doing research! She's not going to go into any situation unprepared, including a bar full of drunk aliens, some of which wanted to proposition her. At least...she suspects that was a proposition? Not everything is universally translated between cultural differences. But that's beside the point, it was totally research!

So yeah, she can get behind a mech who reads user manuals. But really she just wants to get behind him in general right now, and the fact that she can't is making her plating tight in uncomfortable ways. It's making her grumpy too, and said guard is the unfortunate easy target. "Yeah well, maybe I don't want grace you with the opportunity anymore, mood killer!" Someone(s) here is a real killer and spoiler: it's not that stupid security guard.
