We had a number of guys who were used as Chairman, who would thank the speaker,and then say "our thanks goes to the FDS for the outline"
I used to point out how inappropriate it was to use such an esoteric expression at the close of a Public Talk, but I don't think those guys had the brain cells needed to think up their own words, or the education to know what esoteric meant.
I think most speakers felt there would only be " persons of interest " apart from Dubs present, so gear the talk mainly at the majority, already brain-dead. certainly a lot of what was spewed on the platform would have astounded and sometimes incensed members of the Public.
