Stop Commenting On Women's Appearance

A few weeks ago, while I was boarding a plane, one of the male flight attendants was checking me in. He looked at my passport, looked back up at me, and said "I like your hair better blonde. You should dye it back." My jaw dropped. What gives him the right—the entitlement—to comment on the way I look⁠, let alone tell me which way he prefers I look? I am not there for his consumption!
