The mental image of Jailbreak skipping about on the moon actually manages to get a small cackle out of Garrett, disarming his already-weakened senses long enough for him to stroll into the café without actually noticing that his potential partner in crime has just politely held the door open for him. He's putting everything he has left into saving face at this point, but not even a rigorous afternoon of purse pinching is enough to compensate for a failing body and dulled awareness. He probably doesn't even realise how bad he really looks.

"...it's like we're walking into some prince charming's fancy castle. I wonder where they're storing all the spare knights in shining armour...?"

...he's still himself enough to continue snarking, at least. And though he moves through the building a little too quickly, missing a corner or two where an assailant could be hiding, and though he doesn't so much sit in his chair as collapse into it...he does nevertheless acquire a table for him and Jailbreak that is a healthy distance away from any of other patrons.
It then occurs to him that he's supposed to be here because there was a promise of food, so he instinctively attempts to sit back up again, already planning out how to best purloin the nearby display of its pastries. Old habits die hard.
