Yeah, in my rural area Jehovah's Witnesses occasionally show up at the door. Mostly handing out printed leaflets. One time someone who looked very meek and shy gave me a painstakingly handwritten letter in blue biro that must have taken them ages. I did read it after politely saying thanks and goodbye, and it was thoroughly unhinged and extreme oceans-will-boil-with-blood doomsday Revelations fanfic.
Cities get a lot more interesting. Walking round That London or Bristol, for example, you may well be accosted by anything from charity muggers to scientologists to people with more individually idiosyncratic convictions. I just solve it by never ever making eye contact and pretending to be deaf tbh, because I find the process of getting out of the conversation once they've engaged to be deeply embarrassing.
