One other quick point on the original topic: normally I tend to be of the "live and let live and mind my own business" persuasion unless it has a direct, personal impact on me. But on a recent cruise we were up in Cabanas at lunchtime, and very near us, in my line of sight, a certain gentleman was having lunch wearing nothing but swimming trunks. I'm not the modesty police, but it was a bit jarring, and I'm not entirely sure it was the most sanitary situation either. None of the crew said anything, though.
