Nor I, but then again it takes a lot to offend me really. Unless someone is in my face, directly focusing on me, I am usually oblivious to what people are wearing and even if it were aware I doubt that it would bother me in the least. I used to know this old guy who's favorite saying was... "you go to your church, I'll go to mine."
Do they even have a published dress code for there anymore? I have seen one for over at the Grand Floridian, but not in the California Grill. Heck, the name California Grill does not exactly scream formal. I still think that at some point in time we all need to check our calenders and realize that this is the 21st Century. If you look at the old photos of people visiting Disneyland in the 50's the men were wearing suit and tie and the women were wearing dresses and hats. In other words, their Sunday best! Do we really want to go back to that time?
I will admit that there are some folks that shouldn't wear shorts even in their own homes. It is not always a good look. Personally, I have legs to die for (muscular and manly) so I wear shorts merely to give everyone something pleasant to look at.
