I suspect that in a coffee shop in a good area, it really is this easy, male or female.  People are generally pretty social if everyone is on equal footing, not obviously busy, and not creating discomfort.<p>Anyone who&#x27;s tried to get petitions can attest that doing this on a street corner is a much different beast, but I think hallway testing (or lead finding, or whatever else) is more viable than most people think.<p>I&#x27;m also reminded of the study about asking people for their seat on a subway - it&#x27;s almost impossible to <i>ask</i>, but surprisingly easy to <i>succeed</i>.
