Another thing. We're commanded to also make disciples. How can street preaching make disciples? After they're saved, tell them to find a church and go there? That's why I am leery of this practice. Its more than just presenting the lost the gospel, but also to make disciples.
The missionary friend had good tracts, (taught the basics for coming to Christ), plus included his contact information, and the address of the church he goes to, just in case they'd go to the church, but wouldn't want to call him personally. They could meet up again at church, or not, whatever the receiver wants.
BTW, that's also about 10% of the members of our old church. He is how they found our church, and we were an accepting group, so chances were good, you'd be invited for brunch after service (or potluck dinner, depending which Sunday.) And the invite included we'd pay, so we really did get to know people quickly. Nothing like talking about God and life over some pizza, pancakes, or calamari. (Calamari -- always something interesting to watch people eat, and ask them why in the world would you eat squid when it looks exactly like squid. lol)
