Reminds me of my partner and I's story of "Two Knives Guy"

So we're looking for a place for dinner downtown at dusk and this kind of guy starts following us. We are just outside one of those bustling Italian places where there's this outdoor seating lit by brewer's cable and there's like a whole bunch of people milling about waiting for tables or drinking. We are just at the edge of the crowd when behind us the guy calls for our attention.

We turn and he has a knife in each hand, one trained on either of us. I tense thinking that okay - it's a VERY short run to safety but I am not leaving my partner, if this guy attacks I'm protecting my man. The mugger gives us his best glower and goes "GIMMEYRMMMMERRGGR"

My partner blinks as though confused by his intentions "Umm... What?"

I feel like face-palming.

"GIMMEYRMMMMERRGGR!!! "

"I... sorry what are you asking?"

The guy just looks at us like we're complete idiots he turns to me and I just shrug. He tries one more time and my partner just goes "I don't understand..." and the guy, who realizes somebody in that busy establishment is gunna notice what's going on eventually just growls, feigns a slash at my partner and runs away.

When we were talking about it over dinner we broke the interaction down and we were like. The guy had a knife in each hand... If we tried to hand him something how would he take it? I dunno if we rolled a 20 or if the guy rolled a nat 1.
