Normal
When you are on land and a place wants you to wear a jacket and tie and you do not want to, then you go somewhere else, right. It is the same on the ship, there are other places to eat that do not require a suit and tie and he can be happy. It depends on the ship, I have seen people turned away for not dressing according to the guidelines, and other times people have sat at our table on formal night with a gulf shirt and slacks. So you never know for sure. I have seen many forms of dress on formal night.
