I find it hard to fathom why some passengers chose to wear their hats in the restaurants. I would have thought that the maitre d' would have something to say about the practice however apparently not. In the past (on the Wind and Dream at least) there used to be a sign requesting patrons to "please remove headress". Jeans of all kinds are very common in all the restaurants on the Jewel including Cagney's and Le Bistro. It is a little strange to observe tux and jeans together. It is freestyle and the system does work well.
