They still go plodding slowly - "in the most urgent work to save mankind" - door to door - but they choose the time that is least likely to meet anyone. Apathetic low end rank and file (typically one third of the cong) will go out on Saturday mornings or mid week mornings when people are in bed, at the shops, working or off for the day.
Keener rank and file (including retired elders and those that occasionally aux pioneer at a pathetic 30 hrs) will go on each others return visits and bible studies to increase their time and will stand next to a local dummy cart from time to time.
The regular pioneers increasingly stand like stupified dummies next to metropolitan crap carts too. Oh and they'll study with Sister Gotmoorkids children and teens to "help" them (and get their time in).
The only men that go out in the early evening to find people home are the odd ball keen slightly deranged type which average one or two per congregation.
It really would be a joke if it wasn't a complete waste of time.
