Unique business proposition for you

Where do these guys come from!!?
It seems like I always attract desi pyramid-scheme marketers in malls, gas stations, movie theatres etc. It's like I have a neon sign saying "Scam Me!" on my forehead.
Here's the general modus operandi -
You're walking through a mall and you stop outside the Aldo window, wondering how the new extra-long Nygels will look on your feet. Someone clears his throat behind you to attract your attention.
"Excuse me..." It's a chubby desi guy with a surprisingly attractive wife who's beaming away at you.
"Yes?" You slowly drag your eyes back to the guy.
"Are you from India?"
Duh!.. No, I'm Swedish.
"uh... yes"
"I think I've seen you at the temple before."
"What temple? I've never been to any temple." You don't want to seem unfriendly to fellow countrymen, so you attempt to keep smiling.
"Oh... might be someone else. " He's unfazed. "My name is Ashok and this is my wife Deepti."
"Hi Deepti" How the hell did this dimwit snag a woman like this?
After a couple of minutes of banal conversation - where from? how long in the US? etc. - he gets to the point.
"I have a unique business proposition for you." Alarm bells go off in your head. "I run my own online marketing company and I'm looking for a partner."
Sonofabitch!! They're bloody Amway scamsters! So that's why this silly cow has been grinning away at me.
"For a small fee, you can be a part of this great marketing concept." He goes on, oblivious to your red face. "You can work at it after hours, it won't take much of your time. By the way, who do you work for now?"
"I work for the INS. Immigration control. By the way, what is your visa status? Are you here legally?"
You search around for rocks to hurl at them as they flee in panic.
I mean honestly! Where do these guys come from? This is the fourth time this month, always a different approach, but always the same dumb line about a 'unique business proposition.' If you make the mistake of giving them your card they'll hound you with telephone calls for eternity, never remembering the curses you heaped on their head the last time they called.
Can you imagine their lives? Skulking around malls, shunned by family and friends, preying on the weak minded.
If you're one of them and you're reading this - SHAME ON YOU!
