>1. Trust hasn't been eroded (i.e. fraudsters/salesmen do not predominate)
I have become much more guarded and cynical in the past few years after a handful of interactions like this. At a bar or restaurant, and strike up a conversation with someone, only to have them, 15-30 minutes later, introduce me to their MLM, FX, Trading Mentor, House Flipping, etc. scam, and then swiftly disengage when I am uninterested.
I'm not a good looking dude, nor am I an extrovert. So I now just assume anyone approaching me in public is trying to scam me.
