This is a sales technique known as qualifying.
But yeah, who in the street would ask you to cut them a check for $6 million,
Thing is people who are new to the internet have never seen such

I remember I tried to hire one of the guys who sent me a scam message about something i was selling on ebay,
I tried to get him to send me wooden carved animals, which he got cheap in his country,

Couldn't resist.
