As combat is joined and weapons drawn, panic ensues. People scream and scatter, pushing over tables and chairs and other people, running from the scene or just milling about if they can't get away.
The 'implements of stabbing' are some sort of mechanically intricate shortspear. If you're not half mistaken, the blade can fold around, turning the spear into sort of kama. Perhaps (un)surprisingly, they react first - they were here waiting for you, after all.
The two nearest enemies - big, burly thugs wearing heavy coats - charge at the one they perceive to be the leader: The one who speaks the most and gives commands.
In the back, the crossbowman fires his weapon, while the last guy throws his spear.

The crossbowman is the lynchpin for what's going to happen, so let's start with him.
BS: (1d100)[64] vs 35 +10 for aim, +10 for short range, for a total of 55.
Damage: (1d10+2)[10] Pen 2 - his bolt is tipped with crystal, and does not count as primitive. There will even be a small AoE, which will blast a few chairs and tables and an innocent bystander.
Spearman:
BS: (1d100)[61] vs 37 +10 for aim
Damage: (1d10)[7] Pen 1 - primitive
Thug 1:
WS: (1d100)[25] vs 33 +10 for aim
Damage: (1d10)[8] Pen 1 - primitive
Thug 1:
WS: (1d100)[4] vs 39 +10 for aim
Damage: (1d10)[10] Pen 1 - primitive
Both thugs go for Xanthia, the Spearman throws at Penny, and the Crossbowman fires at ... well, at your informant, but effectively at Phil.
The thugs catch Xanthia on her back foot, and both land telling blows.
In the background, the waitress is holding up her tray like a shield and looking like she has no idea what to do or what's going on. The barman seems to have disappeared.
