I was taught that if you were under a ceiling, you removed your hat. Also, you were bareheaded during the anthem, and if a funeral procession went by. Heck, we used to pull over to give them room. Not done anymore, folks are too important to show respect.An old cowboy ain't dressed unless he's got his hat on. That don't include inside a building unless it's a bar or a sale barn or such.
Ol hands cringe at seein' wannabe's eatin' in a restaurant with their danged hats on. My Momma taught me better.
