It's a little irritating to see a guy act so shamelessly aggravating, but not much more than that. Raihan is more concerned with keeping Turing safe than anything else; he doesn't know if the stranger is actually going to escalate it to something more than words.

"You called them 'useless', if I heard right. Most people would say that's a pretty crappy thing to do!"

He definitely doesn't like the way that he's inching closer to Turing; he takes a couple of strides into the room, putting himself between the robot and this potential loose canon. Call it the instinct of a person that's used to being a protector.

"You know, it's important to be able to read the room. I have a feeling you've overstayed your welcome..." He trails off, glancing down to Turing for confirmation. Do you want him to kick him out? Because he'll absolutely kick him out.
