Ask about the man.
From Create Your Own Story
If you're going to risk taking drinks from strangers, you might as well make them a little less strange. Tracing the circumference of your mystery drink with your left index finger, you motion across your arm with your free hand and point, mouthing: "Who's that?"
The stern face of the cyborgian bartender breaks into a subdued half smile, and his lips barely open. You can't make out the actual utterance that escapes his chrome-plated lips, but it seems like he's said "Null."
You remind yourself to get high-speed ocular implants for lip-reading, because it sure as hell isn't your forte. Before you can ask for more information, the bartender's already serving another customer with the same rapid mechanical motions.
"Null." That a name or a rejection? Great.
Well, maybe "Null" is a regular. That's a start.
