I don’t know what the legal standing is but I remember years ago that clubs and restaurants could, and did demand proper dress such as black tie only, or no polyester allowed, no jeans allowed..
I see on stores signs that say things like “No shirt, no shoes, no service’.
I’ve known of higher end places that might not tell you that you look like a slob, but they wouldn’t come and get you for a table either. They’d either tell you that it’s a 4 hour wait, or just leave you in the lobby till you left of your own accord.
The reason I say ‘years ago’ is to establish that it’s not a new thing as a result in a loss of freedom, but that it has been a customary practice at some establishments for a very long time.
I know that schools, hospitals, and other businesses DO have dress codes for students and employees, and that health ordinances do demand certain dress codes for health and safety reasons, under certain circumstances.
“I see on stores signs that say things like No shirt, no shoes, no service.”
This is a Health Department law not just a store rule!!
