Dear Queenie,
I was raised to believe it is good manners for a man to take off his hat or cap when he comes indoors, but nowadays I see men everywhere wearing their hats/caps inside.
Queenie, have the rules changed?—Headgear Etty Ket
Dear Etty Ket,
According to the etiquette books, the rules have not changed. However, I suspect not so many people are reading the etiquette books as used to be the case.
Also, I have noted that in some business establishments, especially those that deal in food, all employees, both male and female, wear hats or caps that confine their hair, of which I wholeheartedly approve, etiquette or not.
