Uh not correct. Tall angry looking dudes get told all the time to 'smile'.
Of course, it's also aimed at women for sexist reason, I got told to smile so many times as an angry looking dude. Then I'm walking around with my daughter and this full on 30 something grown ass adult man tells her to smile. I could have rage fisted him into the fucking sun at midnight, The pure burning hate that flooded my viens at that moment decreased my life span by 3 years. I could have poured it down his entire being. Instead I told him she'll do whatever she wants with her face, and he can fuck off.
how is that being an asshole? you said it happens all the time and when i asked you said it happened years ago. because i can tell you that most women who don't smile all the time wouldn't say it's been years since some stranger felt entitled to tell them to smile. that's my whole point.
