Do not patronize any business that supports medical segregation.
That's the short term easy fix for this type of unconstitutional behavior.
Next, call the police department & representatives of whatever town you encounter medical segregation and alert them to it and let them know it's unacceptable.
Then go to every online review website and social media platform and inform everyone that that business supports medical segregation.
This is a peaceful and effective way to deal with this unconstitutional bullshit.
