Where I am there are two or three "Metropolitan" carts in the busy hubs of the town fed by the circuit pioneers and other ubers and then each of the congregations has their own cart arrangement in their local shopping centre.
Back in 2012 or whenever it all got started I expressed the view that there wasn't much interest and was told by the service overseer that people had to get used to seeing us and then they would show interest. By about 2014 there was a bit of a buzz in the hall about how people were now friendly. More like the local slackjaw came up and spoke to the sisters from time to time.
Now it is just a way of "getting in time" - as Blondie said "using their worst sheep as sacrifice" before going to the coffee stop.
Utter waste of time and probably counter productive now. No extra "bums on seats" in the KH - no increased memorial attendance - no wonderful examples on the circuit assemblies.
One look at the smiling automatons on jwborg is going to drive away all but the most mentally needy and less useful members of society isn't it?
