“Hey, cool knife by the way.”
”The... Slicer.. knife?”
“Yeah! Knives are more of a Jaxtian thing so, surprised to see your culture have a whole restaurant built around one.”
”...It's a tool for the kitchen. Every culture with metal working would invent a tool like that.”
“Yeah, but, Jaxtian dueling knives are in a league of their own. And you may be good at slicing up fish, but people? In a duel? Well, that's another level of skill entirely.”
”I practiced for years to develop the skills necessary to run this restaurant.”
“And I've been raised from birth to be an expert knife duelist. I'm number three in the whole Hegemony, actually. I can almost rival Halam Anak himself. But only in knives obviously, can't simulate a huge iron staff very accurately...”

The Jaxtian stands there proudly and arrogantly standing on his achievement, despite his being young and with no lanyard or ranks or anything of the sort.

You subtly motion your hand to a coworker to get his attention. The waiter watches your hand as you use your “hunting language”,your sign language; developed for underwater communication by the Swall. You glance at the smug Jaxtian before you, who is too absorbed in himself to follow; though you doubt he's studied hands.

[Who. Stupid. Kid?]
[Monkey. High. Birth. GAR- AS- TRA. Careful]

The phonetic signs are especially uncommon outside of expert signers, but you understood the message well enough. That's just great. You're hoping he's had enough of this cultural exchange and just leaves, but then again, maybe you can instill a valuable lesson? You've had just about enough of him disrupting the high level of professionalism your establishment is known for.
