What was secret about what you were doing in Vietnam is you would have been quite embarrassed to admit to it....and the Bar Girls knew it. You only paid for their Tea and Time in order to maintain the truth did not get out.
The rest of the story is you were always looking for the Page Three Girls in the month old papers.
Just as in Vietnam, while in the BRC hid behind the newspaper, you found it hard to break old habits while you did the Nigerian version of knitting as several heads went rolling over the years there.
