Yes , there were some funny things to put up with in the days when we used to rent halls. I can’t match Simon’s story but....
I remember a Circuit Assembly in my childhood that was held in what seemed to be an army drill hall. At the back of the audience there stood a large field gun of some sort, just there at the hall while we talked of peace on Earth.
When I was giving Public Talks one place had a portrait of The Queen up behind the platform. As the congregation arrived though, someone turned up with a Yeartext board , made to fit and covered it up completely..
A lot of things happened in the past that would not be done now, congregations were more independent and sometimes did their own thing.
