Dude, what the actual fck?!
I mean, maybe they were just some church followers or stuff, and didn't want to hurt or do even something to you but bro... that's the freaking worst method to present something to you, because seemed like if they were going to pull out a weapon or drug or smtg, so I think my advice would be don't deal with them until you see another people doing it and being all just normal.
like one time, I was literally outside. These two huge tall nerd looking (no cap) dudes walk up to me and ask, "HEY BUDDY, YA KNOW STUFF ABOUT GOD???" and I'm like "yeah, wut about it my guy?" and he said "WE WANT TO GIVE YAH A LITTLE SOMETHIN'!!!" he starts pulling smth out his bag really slowly and I was like *imma be right back" went inside and did not even go back out.
