A gentleman does not put his feet on the table and removes his headgear when he enters a building.
The only exception I can think of, would be a uniform L/E on a call entering a building.

To my way of thinking my wearing a hat affects no one unless I am in a theater in which case I would not wear one. If someone chooses to be offended because I have a hat on, that is there problem not mine.
At least I don't wear my pants down where my butt crack is showing and I don't scratch my crotch in public and I don't adjust the hang of my privates in public and I don't blow smoke on others and I don't wear offensive colognes or perfumes and I don't go out all sweaty and smelly, so I consider my wearing a hat to be no problem at all or at the very worst the smallest possible violation of southern tradition.
I also don't let my dog run loose and I don't drive aggressively and I don't go around borrowing things and not returning them and I don't spread rumors and I don't lie or cheat.
How anyone can possible upset themselves because I have a hat on, is beyond my comprehension. I figure they have never been around truly rude people and must be saints themselves, or such arrogant slobs they have to point out the slightest possible social infraction that others make to make themselves feel better.
I mean a hat just sits on my head. It does not make sounds; it does not give off foul odors; it is certainly more attractive than my ugly head; it is not unsanitary; when I wear a hat I wear very nice cowboy style hats or sometimes baseball type caps, but they are all pretty nice head gear.
I have no idea how the social norm of not wearing a hat or cap indoors got started, but it is time for it to die a natural death.
Waving got started to show others your hand was empty and non-threatening. Taking a hat off must have been some way of showing you were not bald to the weaker, fairer sex back before women's lib turned women into men wantabees. However it got started there is no rational for it today.
So if women can burn their bras, I say it is time men were allowed to wear their hats and caps indoors as well as out of doors. Lets have some equal rights for men since no one objects to women wearing hats indoors.
Strike a blow for freedom and wear that hat indoors!
