there was always the odd chap and chapess who might behave in a slightly odd way who would attract attention.
Define "odd"...
For example is it the crew members who miss beer call, claiming they don't drink? Perhaps it's those who tell a tale about not being around in the evening because they are "visiting relatives"? How odd are those who say they were in the gym at 2 in the morning? What about those who go birdwatching - should I be especially vigilant? I'm just asking because I've heard all of the above and lots more over the years and now wonder if I should have reported them? .......
