When I was a teenager the District Convention was going to be held in my city. This was in the 1960s when JWs could go through the Rooming Department" and ask for a room in a private home which was cheaper than a Motel/Hotel.
About a month before the convention all of the pubs. did "Rooming Work" instead of the normal Minestry, myself included. We went from house to house asking people if they would be willing to offer a bedroom and bath to PERFECT STRANGERS for 3 DAYS and NIGHTS for FREE!!!
I went house to house with another teenage girl and was astonished that in less than 2 hours 3 householders AGREED!! The rooming Dept collected money for those rooms but the householder got ZILCH.
