We had business territory in my last cong, where we would go into shops and offices and offer the attendants magazines. I really liked that, much better than door to door because I could also look at the nice things in the shops. The staff also had to be nice to JWs walking in because we could be potential customers so there was no expletives or shut doors.
When I lived in Cairns however, we would do the Esplanade and I hated that, absolutely couldn't approach strangers out on the street with a tract. I can't say I was thrilled about d2d either, but it was much easier to have a door frame around someone when talking to them. Some JWs here love the public witnessing though, like the ones who buy an all day bus pass and spend the day riding the busses and witnessing at the passengers. Most people aren't into that sort of thing; only the more confident and gregarious ones. It's like only certain types of people go into sales and direct selling. Most of us don't have the personality to pull that sort of thing off.
Now here on the Gold Coast, Australia, I've not yet seen those carts or stands. I can imagine some JWs would like that because they sit there all day doing nothing, and can easily rack up the hours. I personally would not like to sit at a stand because I don't want to be where everyone can see me. People who value privacy would probably be put off that sort of thing.
