I've been reading all these *watch out* postings that tend to be recycled
rumors.  However, urban legends or not, what happened to not talking to
strangers....or at least not to strangers that approach you in parking lots
trying to sell stuff?

As a rule, never follow anyone that randomly approaches you in a parking
lot, a mall, or anywhere.  Abductions do happen and ,often, they happen this
way.  You are being lured for a reason, whatever it may be.  If this person
says they need help, offer to call for help, but please don't go with them.

As far as selling knock-off perfume  goes, why a parking lot where it
automatically seems suspicious?  I believe a flea -market would me more
conducive to sales.
