Your best comeback to obvious scam panhandlers?

I hate those dudes who roam gas stations & parking lots begging for gas money. Even worse are the ones who sit in a car and send their GF to beg for money. It's a hustle plain and simple - we live in a country with more freebies for the poor than most realize.

So, with that, post your best stories of a quick comeback, a near miss of a physical confrontation, etc. Here's mine:

About 15 years ago, I was headed to the airport with two carloads of people out West. Of course we had to stop for gas. The guys in the lead car were all Dutch, and if you know the Dutch, the shortest was 6' 4". Guy runs up to the car as they get out, all smiles running his hustle - gold teeth told you all you needed to know about how much he needed the $.

First, he gets kind of an "Aw, shite" look on his face as the driver, whose nickname was Two Meter Peter because of his height, unfolds from the driver's seat. But he goes for it anyway, and Peter explains in broken, accented English (his English was actually excellent) that they are all Dutch and have only Euros. Dude waves them off with a "awww, naw man, naw, don' need nunno that".

Hustler then locks onto his next target, my 5' 10" theoretically more manageable self at a different gas pump. I've had time to consider his prior interaction, so I decide to employ some of my more esoteric college classes.

He trots over to me fast talking about jes' needin' $20 to git to work. I look at him with a blank stare. He starts repeating it.

Me: Ya guvaroo Po-Rooski yuiezik, (I speak Russian) English, nyet.

Him: What? Whatchu say main?

Me: I babble about half of what I can remember of Russian words in a meaningless run-on sentence.

Him: Hey look bruh, I jes need twenty dollah, gots to go to work.

Me: More blank look. I point at myself and say "Po-Rooski" (Russian). "English, nyet"

Him: Pulls out a dollar bill to show me, holds out his hand.

Me: My face lights up with understanding, and I deliver my best shite-eating grin. "Aha! Rrrrubles, da?" "I......rrrrubles....nyet.....d-o-l-l-a-r-s" I stretch it out like I have a hard time saying the word.

Him: Throws up his hands and exclaims "Aw, f all this shite, I'm outta here!" He stomps off toward the gas station across the street cussing foreigners every step of the way.
