Should I remove my hat in an elevator? -asked by Lonnie from St. Louis
Our hat etiquette page is pretty clear on this particular topic, so permit us to quote it:
In public buildings, the elevator is considered a public area, and therefore an area where a gentleman may leave his hat on. A gentleman should take off his hat and hold it in his hand when a lady enters an elevator in any building which can be classified as a dwelling. He may put his hat back on in the corridor.
So, to answer your question, you can usually leave it on, unless in the presence of a lady or a very intimate elevator (perhaps such as one in a small inn). Personally, we find some of these rules rather archaic. We wear our hats confidently on any elevator rides we take.
