#hellomyname is Susan, and then something shared, like this is really good asparagus for sale, or did you see the deal on these clothes?  Otherwise just saying hello in a warm tone is an open door to begin an outreach.  I see this as usually looking for common ground, shared experience, or a request for help or information.  I was in college during the hitch hiking era, and it was a little iffy, after jumping in a strangers car, you say something like,,,,I hope you are nice  LOL.  Well it doesnt take that much trust, but push your comfort zone.  You might get no where within it. Every day on my block I am saying, no you cant have a dollar, sorry.
