A gentleman usually removes his hat indoors, or should.
Yep.
I always think of Bum Phillips...
**As coach of the Oilers, he became the winningest coach in franchise history (59-38 record). He was known for his trademark cowboy hat on the sidelines, except when the Oilers played in the Astrodome or other domed stadiums. He stated that his mother taught him not to wear a hat indoors; his former boss Bear Bryant similarly refused to wear his trademark fedora during indoor games.
That's how I was raised. Gentlemen remove their hats while indoors. Glad to know that some folks like onedoug have manners.
WHY SHOULD A HAT BE REMOVED?
Exactly WHY ?
