Replying to Mormons in helmets and ties just tried to convert me...

So, right now I'm sitting in a park, on a bench, mooching off of Panera's free internet... and these two guys come over. They are both tall, blonde, and wearing black helmets, white shirts, and ties etc...

I'm just trying to mind my own buisness, shooting shit on this here lovely website, and they decide to surround me, sit on either side of me, and ask me about god, and tried to introduce me to mormanity (mormanism? morman religion? whatever you wanna call it..) When I kindly shoo'd them away, and told them I was busy "newschooling" haha, they would not leave unless I took this small book from them. I kindly refused at first, but and the guy stood there for like 2 mins, no joke, (so I kinda rudely, and very sarcastically told them "I dont read homie" haha). Finally the guys left, probably to disturb the next individual.

I dont understand this move... I mean, how on earth do you expect me to just put down what I'm doing and talk to you after you creepishly surround me and start shooting off your beliefs in my direction... I've never been approached this way by anybody for any reason... Is this how mormons USUALLY work?
